Wanted: Assorted OLD Paint-laden Bristled Brushes

I have a project in mind but we will need about 30 old, dried up, worn out paintbrushes. You know, the kind you used to paint window trim or maybe a piece of furniture and forgot to clean. The yuckier, the better! Please send any brushes you'd like to donate to school with your child. I'll have a collection box near the office.

Thanks for your help!
