I'm not sure why, but I don't usually do a lot of things in stripes. I was inspired to give stripes a try when I sat across from Anita, of Anita K Designs, at the Mammoth Cave Retreat. She was using long bolts to make texture on striped slices, and I really liked the way they looked.
The next striped pieces I made were passed through the pasta machine just once to seal the joints between the colored stripes. Since the bolt ridges only run in one direction, each piece is rolled twice, once each in perpendicular directions. The clay does move a bit while being rolled, which I think adds to the interest of the sheets.
