I am cutting strips from fabric left over from previously made quilts. Some of them are from nice bright colored quilts, and some are from more earth toned quilts. My questions is how do sort the different colors for strip piecing? Do you still just pull the strips out and sew them on as long as the colors don't clash or are the same as the previous strip? In case you can't tell, this is my first scrap quilt. Appreciate any help given.
