Arts Collaborative Medford, the new community arts center on Mystic Avenue, is offering a Stitch Resist Shibori workshop led by Medford artist Christine Willis. In the workshop, you’ll explore stitch-resist shibori dyeing techniques and make a one-of-a-kind tote bag. With stitch-resist the patterns are created by using a needle and thread to “draw” on your fabric. The stitches resist the dye, creating patterns and color variations. Once your stitching is complete, you’ll dye your piece in a dye bath, then remove the stitches to reveal your unique design. All materials are included in the $45 price of the class.
