Valley fold

A valley fold is the first simple fold, in which the paper is folded in front of itself. The valley fold — which most people do as “just fold the paper in 1/2” — is virtually made from substeps. These steps assist fold the paper very precisely, that is vital in complicated fashions. Here is one manner to make the valley fold very precisely:

Pull the lowest aspect up and forward.Loosely fold, with out creating a crease.

Line up edges.

Line up a corner (by means of lining up the rims on one facet, and lining up the edges on the other facet).
Hold (a loosely folded, uncreased) paper down to prevent slipping.
While keeping the paper down so it does no longer slip, spread out a flat region on the paper. This is frequently carried out with the aid of retaining the paper down at edges together with your index arms. Also hold down the paper with one (or each) thumbs. Gradually circulate your thumb(s) far from your finger(s), pushing your thumb into the paper, but pulling the paper taut among your thumb(s) and your fingers.
Pinch a crease. While maintaining the paper down so it does no longer slip, spread your thumb(s) a ways sufficient from the brink that they reach the meant crease line.
Resolve the crease. Without letting up at the paper, keep the spreading motion until the crease is sharp. The crease have to be precisely wherein you intended it to be, without any waviness within the facet, with none “bubbles” within the layers of paper, and with none slipping of the paper at the brink(s) or corner(s).
Mountain fold

Mountain fold

A mountain fold is a whole lot similar to a valley fold, except in one admire: it’s far within the contrary course. This can gift problems with the folding order, as valley folds are every so often achieved when there are other layers of paper beneath and the paper can not merely be became over. Therefore, to complete a mountain fold, these instructions must be accompanied:

Summary: fold the paper at the back of itself

Lightly pinch the paper alongside wherein the crease may be.
Pull the bottom of flap to be folded at the back of itself, however with out trapping different layers of paper among them (this is simplest a problem if there are flaps at the back of the phase to be folded, and can be averted if the flaps are pulled apart a chunk to open them and provide you with more area to fold)
Line up the pinch marks with the edges of the paper.
While protecting the paper down so it does not slip, unfold out a flat vicinity on the paper. This is regularly finished by way of protecting the paper down at edges together with your index fingers. Also keep down the paper with one (or both) thumbs. Gradually pass your thumb(s) faraway from your finger(s), pushing your thumb into the paper, however pulling the paper taut between your thumb(s) and your fingers.
Pinch a crease. While preserving the paper down so it does no longer slip, unfold your thumb(s) a long way sufficient from the edge that they attain the supposed crease line.
Resolve the crease. Without letting up on the paper, keep the spreading movement until the crease is sharp. The crease need to be exactly in which you supposed it to be, without any waviness within the side, without any “bubbles” inside the layers of paper, and with none slipping of the paper at the threshold(s) or corner(s).
Simple compound folds
Simple compound folds require simultaneous valley and mountain folds but the creases can be made earlier than the real folding.

Inside opposite fold

Inside reverse fold
An internal opposite fold includes radial mountain folds extending from a unmarried point on a important fold, and a reversal of the significant fold at the affected give up, all performed simultaneously. Here is one way to do the inner reverse fold:

Start with a flap. Decide wherein you want to make the inner reverse fold.
Valley fold the paper alongside the selected line.
Unfold to step 2.
Separate the two hidden layers of paper, so that you are half of-manner among step 1 and step 2. You will see the vee-formed pair of creases shaped in step 2.
Push the top of the paper into the space you just made.
One of the creases (of the vee) will already be in the ideal path (a valley fold as visible from inner; a mountain fold as seen from outdoor). The different crease could be within the contrary path. Reverse the second one crease, in order that both creases are valley folds as seen from the interior, and [mountain fold]s as seen from the outside.
Reverse the decrease left part, so that it’s far a mountain fold as visible from the inside, and a valley fold as seen from the out of doors.
“Pop” all three creases into vicinity.
Close up the version once more.
The internal opposite fold is performed. (Notice how you reversed the folds to place the top within the version–as a result the name.)
Outside opposite fold

Outside reverse fold

An outside opposite fold includes radial valley folds extending from a unmarried point on a important fold and a reversal of the middle fold on the affected cease, all performed concurrently.
Low-intermediate abilities
Low-intermediate abilties require simultaneous valley and mountain folds however no longer all the creases may be made before the real folding.

Squash fold

Squash fold carried out to 1 flap of a waterbomb base
The squash fold starts with a flap with at least layers.

Make a radial fold from the closed point down the center of this flap.
Open the flap and refold downward to make two adjoining flaps.

Rabbit ear fold

A rabbit ear fold starts offevolved with a reference crease down a diagonal. Fold two radial folds from contrary corners alongside the equal facet of the reference crease; the resulting flap have to be folded downwards in order that the preceding edges are aligned.

Rabbit ear fold

A petal fold starts with connected flaps, each of which has at the least two layers. The flaps are connected to every other alongside a reference crease. Make radial folds from the open factor, so that the open edges lie along the reference crease. Unfold those radial folds. Make some other fold across the top connecting the ends of the creases to create a triangle of creases. Unfold this fold as nicely. Fold one layer of the open point upward and flatten it the use of the existing creases. A petal fold is equivalent to 2 facet-via-aspect rabbit ears, which are linked alongside the reference crease.
