I am going to make a country patriotic quilt that has a piece of red fabric from Connecting Threads. I am going to prewash it with retayne because I don't want any chances of it fading after the quilt is finished. It is a very complicated quilt, at least for me, and I don't want to spend all the time and money making it to have it ruined by fading fabric. I will serge the ends of the fabric first though.
Side note: I bought some of Connecting Threads thread and just love it. My sewing machine is a little picky about thread and this thread works great in my machine. Very little lint.
