I am one of the vendors...I was also there last year.
I have mostly jewelry but also a few other items. I tend to use recycled materials like soda tabs for belts and bracelets, t-shirts for aprons and small tote bags, and plastic soda bottles and duct tape for bangle bracelets. I also have some standard beaded bracelets, necklaces and earrings, and a few crochet and knit hats. Hope to see you there!
