I had just finished up my Whedonverse Craftster swap last week with my 13 year old son constantly asking "can you make me one of those?". I told him he'd have to wait and gave him a couple books to look through in the meantime, Plush You! and Softies.
These books had him laughing at all the goodies. He asked me if I could make him some of these too...the Dollop, of course - he is a 13 year old boy after all. I said NO, make it yourself. That's me - DIYODS!
So he did. But he started with his own creation based on a Goomba and Bullet Bill. I think they turned out great. He is now working on a skull.
...note: my felt goodies from the swap will be posted once my partner receives them :)
