Origami! folding paper to make nice shapes or animals or flowers... anything.
Did this a lot as a kid. Gave a lot of it away to my friends.
I don't do it too much now. Maybe I don't have the patience/focus any more.
I like a lot of the stuff I made before. This bird and flower ball are some of my favourites.
The staple basic origami piece. Probably the first thing you should learn.
These can take a long time. Usually a whole day if you just sit there.
