This origami tech tree shows how most origami skills are related to each other. It also shows which skills are harder, because they use lots of other skills. (This page needs LOTS of pictures, and maybe some animations.)
A few examples, to start off:

Pureland Skills
Pureland origami can be done by just folding one thing at a time. It has no simultaneous folds a la the squash fold or waterbomb base.
There are other ways to make a mountain fold, but the result is the same.
= Fold in half (rectangularly). Unfold. Fold the edges to the centerline.
= Fold in half (diagonally). Unfold. Fold two edges to the centerline. All 3 creases meet at 1 corner.
Simple Skills
= valley fold an "X" and mountain fold a "+", all at the same time.
= an inside out preliminary fold.
= valley fold a "+" and mountain fold an "X", all at the same time.
= an inside out waterbomb base.Low Intermediate Skills
= start with a triangular flap with 2 layers (for example, part of a waterbomb base). Make a particular valley fold, unfold, open out, reach in, and flatten. (Some of these "trivial" steps are described on the valley fold page.)
= 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.
