I don't make the models (not quite that artistic, unfortunately), but you can download the Pokemon models from here: Paperpokés - Pokémon Papercrafts

I also found the Sonic model here: https://archive.org/details/SonicPapercraft

Marvelous.

I used to do it, not now because... I don't really know why. I really liked big models, but the paper you needed to do them was quite expensive.

Wow, that's pretty good! Whenever I do something like origami, I always get stuck on some step even if following a very descriptive tutorial :D It's pretty impressive that you can do something like this.
