We had an Art Quilt Guild that met at our shop. Some of the mediums used were: Shiva Paint Sticks, Tyvek, Texture Magic, thread painting, etc. Some of the ladies hand-dyed their own fabric. Some of the ladies attached non-fabric things onto their quilts, everything from beads to metal washers to parts from a bra. There are several online art quilt forums.....hope this helps!
