Hey guys, this is Evan from EZ Origami! And today I'll be teaching you how to fold an Origami St.

George's Cubedesigned by Francis Ow.

This is a simple modular model and it looks great whenit's completed.

This model requires seven square sheets of paper.

Each unit isfolded from a rectangle with a dimension ratio of 3:4, so beforefolding the unit's, I'll show you how to cut each square to the correctdimensions using a folding tool.

You'll need six squares to fold the units, andyou'll need an additional square of the same size for the folding tool.

So you'llneed a total of seven equally-sized squares.

I recommend using six inch squares tofold this model.

Using six inch squares will result in a cube with a side lengthof 2.

25 inches.

I'm going to be using larger paper withcolor on one side and white on the other just to make it a bit easier to followalong.

And we're going to start by making the folding tool.

So take one square and make sure it'sthe same size as the other six squares that you will use for the units.

And onceyou have your paper, start with the white side up.

And thenwe're going to fold in half vertically.

So take this right edge and fold it overto the left edge.

Align the corners and the edges, thenmake your crease, and we're not going to unfold.

Instead, we're simply going to rotate thepaper 180 degrees so that the folded edge is now held on the left.

And we'll use this as a folding tool to help cut the rectangles for the units.

Soonce you have this, then we're going to take one of the six squares that weprepared for the units and we're going to hold it with the white side up.

Then what we want to do is pick up thesquare, and we're going to slide it in between the two layers of the foldingtool.

And we're going to push it over to the left as far as it will go.

Once the left side of the square alignswith the left side of the folding tool, you should have something like this.

Thenwe're going to fold over the right edge of the square and align it with thecolored edge of the folding tool.

So we're going to do that by firstlifting up the right side of the paper, and we're going to pull it over to theleft until both edges are completely aligned.

And once everything is aligned,then you can make your crease all the way across.

And once you've done that,then you can pull the square outside of the folding tool, and you should havesomething like this.

And for now we're going to put the folding tool aside andfocus on the first square.

And what we want to do is simply unfold the flap that we just folded in.

So we'resimply going to fold that flap over to the right.

And what you want to do is cutthe paper along the crease that we just created.

And once you've done that, thenyou'll be left with these two rectangles.

And what you want to do from here is putthe narrow strip aside, and we'll be focusing on this 3:4rectangle that we'll use for the units.

And once you have your first rectangle,then you want to repeat the same process on the remaining five squares that youprepared for the units.

And once you've done that, you should be left with sixrectangles with the dimension ratio of 3:4.

And now we're going to modify thefolding tool to help us fold the units.

So for now we're going to put the sixrectangles aside and instead focus on the folding tool.

So first what we want to do is simplyunfold the folding tool so that we're back to the original square.

And nowwe're going to fold the right edge over to align with the center vertical crease.

So we're going to do that by pulling the right edge over to the left, just likethis.

And once the entire edge is aligned with that crease, then you can make yourcrease.

And once you have this, then you can unfold.

And now we're going to foldthis right edge over to align with the vertical crease that we just made.

And we're going to do that by first pullingover this right edge, and once the entire edge is aligned with that vertical crease,then you can make your crease.

And your model should look like this.

Then you canunfold.

And now we're going to fold this right edge in to align with the centervertical crease just like we did before.

So we're just going to fold over theright edge along an existing crease.

And once your model looks like this, thenwe're going to rotate the paper 180 degrees.

And then you'refolding tool is complete.

And once you have this, then we're ready to fold theunits.

So we're going to put the folding tool aside, and we're going to start withour first 3:4 rectangle with the white side up.

We're going to hold it long ways likethis, and then we're going to start by making a small reference crease on eachside of the model.

So we're going to start by folding inhalf horizontally.

So we're going to take this bottom edge and fold it up to thetop edge.

Align the corners and the edges, and thenwe're not going to crease all the way.

You just want to make a small referencecrease on the left, just like this, and then you want to do the same thing onthe right.

And once you've done that on both sides, then you can unfold.

And nowwe're going to fold up the bottom edge and align it with thesetwo reference creases that we just made.

So we're going to start by pulling upthe bottom edge, just like this, and once the edges align with both of thosereference creases, then you can make your crease all the way across.

And once youhave this, then you can unfold.

And now we're going to rotate the paper 180 degrees.

And then we're going to do the same exact thing.

So once again, we're going to fold upthis bottom edge and align it with those two small reference creases just like wedid on the other side.

Again, pull up the bottom edge, and once it's aligned withthose two small creases, then you can make your crease all the way across.

Andonce you have this, then you can unfold.

And now we're going to need the foldingtool to make some important new creases.

So we're going to start by sliding thisrectangle in between the two layers of the folding tool just like we did before.

And we're going to do that by picking up the rectangle, and we want to slide it overto the left until the left edge of the rectangle aligns with the left edge ofthe folding tool.

And once everything is aligned, then we're going to fold theright edge of the rectangle over to this vertical crease on the folding tool.

So we're going to do that by pullingover this right edge, and once the entire edge is aligned with that vertical crease,then you can make your crease.

And once your model looks like this, then you canunfold and slide the rectangle outside of the folding tool.

And now we're goingto rotate the rectangle 180 degrees.

And then we're going todo the same exact thing.

So once again we're going to pick up therectangle and we're going to slide it inside of the folding tool as far as itwill go.

And once everything is aligned, then we're going to fold the right edgeof the rectangle over to the vertical crease on the folding tool.

So we're just going to pick up thisright edge, pull it over to the left, and once the edge and the crease arecompletely aligned, then you can make your crease.

And once you have this, thenyou can unfold.

And then slide the rectangle outside of the folding toolonce again.

And then we're going to turn the rectangle over.

And now you can seethat we've created the two creases that will need to create the color strip onthe completed unit.

And now we're going to create two new creases in a similarway.

So once again, we're going to pick upthis rectangle and we're going to slide it inside of the folding tool as far asit'll go.

And once everything is aligned, then we'regoing to fold over this right edge.

And instead of folding it to this verticalcrease, we're going to fold it to this colorededge here.

So once again, simply pick up the right side of themodel, and pull the edge over to the left.

And once the two edges are aligned, thenyou can make your crease.

And once you have this, then you can unfold and slidethe rectangle outside of the folding tool once again.

Then we're going torotate the rectangle 180 degrees, and then we're going to do thesame exact thing.

So once again we're going to pick up therectangle, slide it inside of the folding tool as far as it will go, and onceeverything is aligned, then we're going to fold over this right edge and align itwith this colored edge here.

So once again, pull over the right sideof the model.

And once both of those edges are aligned, then you can make yourcrease.

And once you have this, then you can unfold and slide the rectangleoutside of the folding tool one last time.

And now that we've made all thenecessary pre creases.

So we can put the folding tool to the side, and now we'regoing to fold in the right edge of the rectangle and align it with thisrightmost vertical crease.

So we're going to do that by simply pulling over thisright edge, just like this.

And once the edge is aligned with that crease, then youcan make your crease.

And once you have this, then we're not going to unfold.

Instead we're simply going to rotate thepaper 180 degrees and then we're going to do the same exact thing.

So once again, we're going to fold overthis right edge and align it with this rightmost vertical crease.

So we'resimply going to pull the right edge over just like we did before.

And once theentire edge is aligned with that crease, then you can make your crease.

And onceyou've done that on both sides, your model should look like this.

And nowwe're going to pleat along existing creases.

And we're going to start with this rightmostvertical crease here, and what we want to do is fold it over to the right alongthe crease that runs underneath this white edge here.

So we're going to dothat by first pinching this crease from the top just to make sure it's amountain fold, and then we want to push the left side of the model over to theright along that existing crease just to flatten everything out.

And once you'vedone that, your model should look like this.

And if you lift up the model, it shouldlook like this from the side.

And now we're going to do the same thing on theleft.

So once again, we're going to fold thisleftmost vertical crease over to the left along the crease that runsunderneath this white edge here.

So we're going to do that by first pinching thiscrease from the top just to make sure it's a mountain fold.

And then we want topush the right side of the model over to the left just to flatten everything outalong that existing crease.

And once you've done thaton both sides, your model should look like this.

And if you pick up the model and look atit from the side, then you can see the new pleats that we just created.

And nowwe're going to turn the model over.

And now we're going to fold in the top andbottom edges along these two existing horizontal creases.

So we're going to start with this bottomedge here, and we're going to fold it up along this bottom horizontal crease.

Sowe're simply going to fold up the bottom edge, just like this, and then we want toreinforce this crease through all layers, just like this.

And then you can slightlyunfold that flap just so that it's held at a 90 degree angle, and once you havethis then we're going to rotate the paper 180 degrees andwe're going to do the same exact thing.

So once again, fold up this bottom edgealong this bottom most horizontal crease.

So just fold it up like this.

Again, youwant to reinforce that crease through all layers, and then you can slightlyunfold the flap that we just folded in so that it's held at a 90 degree angle.

And once you've done that on both sides, then you can turn the model over, andthis is one completed unit.

Now you must fold five more.

Once you folded all six units, you'regoing to need two to start the assembly.

Then look at one and you'll notice that ithas a flap like this on each side and also has a hidden pocket underneath thiscolored strip here on each side.

Then we want to take a second unit, and what wewant to do is slide the flap from the second unit underneath the colored stripon the first unit.

So we're going to do that by firstpicking up both units, and then we're going to slide the second unit's flapunder the first unit's colored strip, just like this.

And you want to continuesliding both units together until they don't want to go any further.

And once both units are aligned, youshould have something like this.

And now you've connected two units.

So from here,we're simply going to rotate the model so that the second unit is now held ontop.

And now we're going to add the third unit the same way.

So once again, we're going to start bysliding the third unit's flap underneath the colored strip on the second unit.

So we're going to do that by picking upall three units, and again we want to slide the second and third unitstogether just like we did before.

Again, continue to slide the unitstogether until they're completely aligned, just like this.

And then you'll notice a trapped layerunderneath the third unit here.

So what we want to do is carefully pullthat flap out from underneath, just like this.

Then we want to slide the firstunit's flap underneath the colored strip on the third unit.

So we're going to do that just like wedid before.

Again, bring the first and third units together, just like this.

Andyou want to continue sliding them together until all three units arealigned.

And once you've done that, then you've connected three units.

And now we're going to add the fourth unit the same way.

And we're going to do that by firstrotating the model so that the third unit is now held on top.

Then what wewant to do is slide the fourth unit's flap underneath the colored strip on thethird unit just like we've been doing.

So you just want to bring the third andfourth units together, just like this, and you want to continue sliding them togetheruntil they are completely aligned.

And then you should have something like this.

Then we're going to rotate the model so that the fourth unit is now held on top.

And again, you'll see this layer trapped behind the fourth unit here.

So what we want to do is carefully pullthat layer out from underneath.

Be careful not to separate all the units.

Then what we want to do is slide the second unit's flap underneath the coloredstrip on the fourth unit just like we've been doing.

Again, be careful not toseparate all the units.

And you want to continue sliding the units togetheruntil everything is completely aligned.

And once you've done that, then you'veconnected four units.

And now we're going to attach the 5th unit the same way.

So we're going to do that by sliding the fifth unit's flap underneath the coloredstrip on the fourth unit just like we've been doing.

So once again, slide thefourth and fifth units together, just like this.

And continue sliding themtogether until they're completely aligned.

And then we're going to rotatethe model so that the 5th unit is now held on top.

And once again, you'll see onthe left side here there's a trapped layer underneath.

So whatwe want to do is carefully reveal that layer and place it down on top of the5th unit just like we've been doing, just like this.

Then again, we want to slidethis flap underneath the color strip on the 5th unit.

So we're going to do that just like wedid before.

So you want to bring these two units together until they'recompletely aligned.

Then you should have something like this.

And now we're goingto connect the second flap on the 5th unit.

And we're going to do that by slightlyrotating the model, and then we want to slide the fifth unit's flap underneaththis colored strip here.

And we're going to do that just like we've been doing by bringing the two units together untilthey're completely aligned, just like this.

And once your model looks like this,then you've connected five units.

And now we're going to rotate the model so thatthe two remaining flaps are now held on the bottom.

And now we're going to addthe last unit the same way.

And we're going to do that by first inserting thelast unit's flaps inside of the model's unused pockets.

So we're going to startwith this strip here, and we're just going to slide these two units together untilthey're completely aligned, just like this.

And now we're going to rotate themodel so that the last unit is now held on top.

And before we connect the secondflap on the last unit, we have to release the two trapped layers from underneath.

So as you're doing this, you carefully want to pull the trapped layers out to either side,just like this.

And once you have this, then you want to place those layers ontop of the last unit the same way, just to keep all the layers in place.

And nowwe're going to connect the second flap on the last unit.

And we're going toslide this flap underneath the corresponding colored strip.

And onceagain, we're going to slide these two units together until they're completelyaligned.

As you're doing this, be careful not to separate the rest of the units.

And once everything is completely aligned, your model should look somethinglike this.

And then to finish connecting the last unit, we simply have to connectthese two remaining flaps here.

So we're simply going to rotate the model.

Andwe're going to slide these two flaps underneath this colored strip just likewe've been doing.

Assembling these last two flaps can bechallenging, so you may have to bend them a bit just to get them under thiscolored strip.

And once you've connected the last twoflaps, then your St.
