I have quite a few pieces. I've been making the Farmers Wife Sampler quilt blocks and have used several of my gray fabrics in the blocks. I think it's important to have a selection of gray fabrics, especially for scrappy & sampler quilts. I always think of "neutrals" as different shades of ecru to light brown; if I am correct, then grays are the other "neutrals"; they work so well with blacks, blues, etc.
