I am learning to hand quilt, so I purchased a pre-printed mini wholecloth to practice on. I was having fun when I realized that all of the wholecloths I see are made with the same color thread. I bought some variegated (Carribean Sea) and I've been using that on natural wholecloth. How big of an oops is that? Will the quilt police show up soon? :) Thanks for all of your help.
