I'm a member of Mixed Mania, a book study group on Yahoo. It's a stretch for me, as sewing and quilting are my comfort zone, and mixed media is outside it. I'm intrigued by mixed media though. I have a toe in the water so to speak, and am trying out various projects as we go.
One swap I've joined is that of exchanging Artist Trading Cards, or ATCs as they're called. These little bits of art (they're 2 1/2" x 3 1/2") can be made from lots of different materials such as fabric, paper, or a combination. Mine are fabric, of course... remember, just a toe in the water so far. They're made on a base of Peltex which is a firm fusible interfacing. They're pieced from fabric strips and then surface stitched with a variety of machine stitches. Once that base was completed, I added different elements to each of them using fabric paints, stamps, small appliques, fabric paper pieces, buttons, and beads. The edges of some are finished with stitched on texture yarn, and others with twisted embroidery floss.
We're making these in sets of five, and can make up to five sets. "Toe in the water" dictates that I'm making just one set for now. But I enjoyed working in the small area, and eventually I'll make more.
