Berryberry I had a big grin reading your step one and step 2. Egad do I ever ever do that? ah hell no. I buy the fabric then figure out what I am making. I figure a yard and maybe a bit of blender and I can use what I have at home to mix up with it. Left overs? ohhh darn! guess I have to keep them. I suppose your doing it the right way but wow I sure do it the impulse way. I am making one now that I bought a half yard of and will just use something from the bins for backing. its got a ton of colors in it parrots red! yellow! bright blue! green! so the thin strip? perfect have some green, oh some pink for those squares in between and well blue backing and I am in! organized? me? NEVER.
