I decided to remake my tutorials for making twistypuzzles, they aren't much different than the first time around, but the first one is quite a bit better I think.

Basic step by step instructions for simple puzzles, pillowing, and modifying.

How to make a megaminx.

Hope they are helpful and I hope you guys like them, if there is anything else I can do let me know.

I would also like to recommend Grigr's puzzle training pack.
