The aboslute favorite of mine is the center of a roll of register receipt tape. They make a really cool radial design. You can see a photo of what I am talking about on my blog, under the clay owls:

I also save lids from markers (not Crayola) that have star-like designs on the end.

Subject: [teacherartexchange] Texture objects for clay
I am wondering everyday objects you use to add texture to clay. I have some great clay specific tools, but am sure there are some less expensive or free items I could be using as well. Any suggestions?
Thanks!
