I've made several string quilts and have really liked how they came out. Yours shows how you don't have to pick a color for the central string (like red, black, or white solid). I did one with pink on one side and purple on the other as well. Thank you for sharing your idea of lights and darks. I'm going to have to make one like yours now! Such a quick and easy way to use up our never ending bins of scraps!!!
