What if I layered each patch with multiple fabrics, tacked them down in the middle, then ran them through the wash to create texture? They came out all nice and wrinkly. Some shrunk and frayed, others didn't. I embellished to emphasize the forms that came out of the wash, sometimes unfolding and stitching pieces down to the background, other times letting them stay curled up and adding detail to the curls.
To keep the emphasis on texture, I limited color in this piece. I used sheers, cottons, burlap, upholstery fabric, and silks to get a variety of textures.
