I was actually going to do rhinestones, but I couldn't find a cheap way to do it. I couldn't find orange and yellow rhinestones.

The only way I could find them was in a $15 bucket of rhinestones.
After I got to thinking about it though, since Smudge's hat is crochet it just fits better to have buttons.

Rhinestones and crochet don't go together very well.
Fluffy's costume is on order and should be coming in the mail soon.
