I have had a jelly roll run. I rinsed them in the sink and my water turned a nice pink. The navy and brown strips made the water a nice mud color. Put them in the dryer and they shrunk and I know how pre cut strips that measure between a two and half and two and a quarter inches. NEVER EVER EVER AGAIN WILL I BUY a jelly roll unless it is all light colors and the blender/background fabric is also light and of the same line. But I am a pre-washer, and always will be.
