I am having trouble with step 15 of Thoki Yenn's DNA molecule located http://theory.lcs.mit.edu/~edemaine/thok/dna42.html.

I can't seem to get from step 14 to step 15 at all; maybe I'm just stupid but it seems quite a dramatic leap.

Any help possible is appreciated.

Thank you.

What you have to do in step 14 is to give volume to the edges of the model. You need to make its edges into T shaped edges Well the T has to be tilted to one side, something like !- body -!

Get it? Is like the thick edge of this picture

Just follow the already exsisting creases. There is a valley fold, fold that over, then fold along the mountain fold.
I folded this model a cupple of times, but I don't have a camera right now

After making a cuple regular ones, I decided to try it with a dollar.

It worked quite well. This is a really cool model, worth folding.
