I have Moda marble swirls in every color except black, which I hadn't seen until recently so now I will add it. When I get below 1/2 yard of any color, I buy more - well, maybe not the pale lilac. Pale blue isn't a favorite, either.
What do I buy I don't need right now - used to be florals, now it's batiks.
What do I not buy - muddy colors, civil war prints, blues if I can help it.
