I have progressed to the point where I don't really care for "controlled" scrappy, where the quilt is scrappy but all the fabrics are from one line of fabric so it's matchy-matchy. I find those quilts, for the most part, rather boring.
Count me as another one who finds Bonnie's quilts busy - beautiful, but busy. However, I don't think it's her fabric choices, I think it's her blocks. Dunster is right, they use small pieces. She usually has alternating blocks, and I've often wondered if you made the alternating blocks with a monochromatic theme, would it calm the quilt down a little?
