Ladies, I"ve read all the post, and am starting these today. But I am still confused or maybe it's a question. I know I use the one focal fabric (valentine) per set of 6. I understand to choose the other fabric ( 4 choices). The question is does the other fabric have to be the same per set. Could I do like 2 red, 2 white, 2 pink, 2 black. or 3 reds and 3 whites. Maybe I need to go take my Cymbalta and read this again. I"m new to all these, so forgive my ignorance.
