I helped do a school fundraiser a few years ago. We made the pen twirlers out of fake fur and pens. Mine were a lot cuter than the ones in this link, but they'll give you an idea. I think they look better without the nose. The boy ones wore a regular tie and the girl ones had a collar and a flower just above the eyes.

Painted rocks would also be a good idea. To do these, you just get some small round river rocks, wash and dry them and then paint with acrylic paints. After that drys, spray with a clear finish.

I can suggest these spoon ornaments. You could hang them from a branch or rod. and sell for $1 each.
Easy to make with bits of felt and paint.

Thank you both these are great. KEEP THE IDEAS COMMING

wal-Mart has been clearancing beads lately. You could string some of these up, wrap some marbles in copper wire, and hang some something on the end for sun danglers. Cheap and cute.
