FYI...I recently made a large batik quilt and in the process of 'fixing' a quilting mistake, I sprayed part of it with water. It bled. After binding, I washed the quilt in Synthrapol with a color catcher. The color catcher came out dark greenish-blue, and my quilt ended up with dye marks throughout it. I tried 'fixing' that by using a color-run remover (which I later discovered is not good on 'fabrics which bleed on themselves'. This severely aged my quilt, washed out a huge amount of color from all of the batiks, left the light areas either grossly faded or splotched with color, and dyed my peach-colored non-batik to a pale green....it was a very disappointing experience. NOW, I wash my batiks well!!! I sent in my strips BEFORE I learned this lesson, so BE SURE TO WASH!!! And, I've since heard that RETAYNE is the best thing to wash them in! Oh, after my experience, I washed even some 2" strips I had for another project. They hardly unraveled at all, and I was still able to use them as 2" strips.
