This time for the Fiberactions-link at right-challenge, we were to use at least 10 colors. Years ago with a partner I had a business marbling fabric for garments to sell in galleries. We marbled rayon and silk mostly. The rayon scraps are in this quilt. I put iron on interfacing behind them then stripped them together rather randomly. When the challenge was posted, these seemed to be a good starting point. I added the vertical bands of blue cotton. The diagonal ones were already in the strips.
