What can we do with felting needles - besides actually make felt? I have materials for you to experiment with, but if you want to bring an old sweater (or piece of one), that would be a place to start. Also pieces of loose and/or sheer fabric, maybe lace, and "fuzzy" fibers. From 6 on, but I'll probably be there by 5.
This is a fun event coming up next weekend at the Sustainable Ballard Festival. Check it out here.
