I've heard that pre-creased origami paper project was launched at Kickstarter (or Indiegogo, I am not sure, to be honest, but I usually surf crowdfunding platforms looking for projects somehow related to origami and learning languages). I remember when I just started folding it was pretty hard for me to break through even simplest models without drawing light lines for folding on the sheet. I am sure many people would be happy if the origami paper they bought were pre-creased. What do you think of it?

Check flower patterns, I'm sure you'll cope with them!!

I watched a tutorial on making paper, but that wasn't origami paper. The process IS time-consuming, but as far as I remember, they didn't use anything super professional or anything you can't buy at a hardware store.

hm29405, mhm, liquid glue on very thin paper may become a disaster. I would say, the thicker the paper, the more liquid can glue be.

tttiger, it all depends on what effect you'd like to achieve. PVA, starch, MC or glue stick.

AnneLore, I don't know which special origami glue you mean exactly, but it should be something like plain PVA.

Of course, you can use glue or starch if you want to keep your models from wearing out. I use glue for exhibition models.
