This spider from Eric Keneeway's book 'Complete Origami' is a fairly easy origami to do. But a little bit of kirigami also comes into play, so origami purists would not be keen on folding this little guy, I suppose.
The origami starts with a a frog base and builds up on that. I folded this from 8-inch square 60 gsm paper. It should be mentioned that there are plenty of layers of folds that go into the model. So thin paper is an absolute must.
