I find C&C to be "lintier" than the other threads. It is also "lumpier". My Vikings don't like C&C either. I also find that C&C weakens over time, and breaks easily. If I am going to be making a quilt that hopefully will be an "heirloom" I want to use the best quality products I can afford. Therefore I will use a high quality thread such as Gutermann, YLI or one of the other better quality threads.
