There are patterns that I do several times, just not one after another. Most of my quilts are given away, so it really doesn't matter that I am doing the same quilt in different colors. Rigth now, I'm making quilts just to use up the stash that I have, so I use any pattern that will work with the color combos that I have. Hence, my like for scrappy quilts.
By the way, your quilts are lovely.
