I totally agree with Jingle. I made a square for a competition. Requirements were that it had to be red,white and blue and the fabrics had to be washed. I was not wanting to wash small pieces, so, I did my block. Put the block in very hot water in my large glass measuring pitcher with 2 Shout color catchers and put this in the microwave for 2 minutes. You should have seen the sheets and the water. The red blead out and the white was white as white could be. Made a believer out of me. :thumbup:
