I'm going to start trying to make my first origami mask from one of Fynn's crease patterns. He offers the crease patterns in different opacities. I'm wondering how I should make my decision regarding opacity? Is it something that I should be thinking about because of the type of Paper I'll be using? Or is it about residual line visibility on the final work? What are the reasons to pick opacity 55% vs opacity 20%?

Wow, I just downloaded a design late last year and then the site went dark. Came back now and everything is free to download and the forums are up. Great work!! I really hope this takes off. Since the forums are almost empty I thought I would throw something out there by asking what would be your recommendation for progressing through your designs. In what order should someone work through the designs. How do you recommend that progression take place? I.e. should you do a mask, then the next? Or re-do the mask multiple times until really good? What paper/card, for each design, etc. I know I'm asking a lot but I'm just throwing questions out there. Online Origami is interesting, you look up origami classes and there are thousands of Crane videos. You search for advanced origami and you get classes to design your own crease patterns. There is nothing in between the two extremes. I think your mask designs are a great in-between as they are somewhat simple (some of the designs) yet beautiful and rewarding. But to use them as a 'course' some more context would be great. Again, great work!!

I am new to the advanced origami world, and I was wondering what software you use.
