I saw this 16 pointed origami star on someone else's blog a while back and thought it looked great, so got round to having a go at the weekend. It was fairly straightforward once I worked out the sequence of folds. Afraid it is rather boring in white, as I used typing paper. They look great using printed paper from a book or something similar. I suppose maps would also be interesting.
The next challenge is to have a go with some stiffened fabric, perhaps spraying it with starch.
