I will be managing Dancing Glass Beadwork in Colorado, and I need a breaker for one hour/day every weekend. You get a pass and $10/day, and will be free to enjoy the festival and/or look for other break work. Give me a call at 720-951-0250 or email besasama@gmail.com, and let me know where you have worked before.
