The Origami Forum

Hi, I'm new here, and new to origami as well. I've only recently begun to fold, and I have a few questions I'm wondering if anyone could help me out with.
I'm wondering if there is anywhere I could find a list of what all the folds are called, and also, if there are some that might go by a couple of different names? Are there any books that might have this sort of information?
Because right now I am trying to find out what a "membrane fold" is, could anyone tell me what that is?

I have moved this topic to the general section. I know, the "How To" Section is a bit confusing, but the explanation of the how to section makes clear what it's all about

May I ask where you´ve read this term? I can´t remember having heard it before.

I can't find that term anywhere on the net so I'm assuming it must be a rough translation of a more well-known term.
I'm making a guess that it's a procedure where you wrap a layer forward that was previously sitting behind a cluster of layers. As if you were pulling a membrane over something. Hah.

hmm... could be a kind of unsink

Thank you for your suggestions! I looked around some more and managed to find this about what membrane folding is:

The membrane fold that I happened across is in step 9 of this dragonfly diagram:

That´s a swivel fold. Begin with valley folding the top flap to the right as far as shown and then flattening the linked paper on the left.
