This origami tech tree shows how most origami folding techniques are related to each other. It also shows which ones are more complicated, because you need to learn more sub-steps to do them. (This page needs LOTS of pictures, and maybe some animations.)
A few examples, to start off:
Turn over.
Unfold.
A precise valley fold = a whole bunch of almost trivial stuff.
A mountain fold = turn over, valley fold, turn over.
A book fold = a valley fold that resembles turning the page of a book.
A waterbomb base = simultaneously valley fold an "X" and mountain fold a "+".
A preliminary fold = simultaneously valley fold a "+" and mountain fold an "X".
A squash fold = start with a triangular flap with 2 layers (e.g., part of a waterbomb base). Make a particular valley fold, unfold, open out, reach in, and flatten. (some of these "trivial" steps are part of the valley fold.
A petal fold = start with a triangular flap with 2 layers (e.g., part of a waterbomb base). Make a different particular valley fold, unfold, squash fold, inside reverse fold 2 edges.
Repeat xxxx on rear = do xxxx on the front. Turn over. do xxxx (or maybe its mirror image) on the rear. Turn over.
A bird base = preliminary fold. petal fold. repeat petal fold on rear.
... (more complicated techniques) ...
Some more detailed notes
- Turn over the sheet of paper.
- To make a Mountain fold: Turn over the paper, valley fold, and turn it back over. There are other ways to make a mountain fold, but the result is the same.
- Book fold. A kind of valley fold. Turn over a flap, just like turning over a page in a book.
