I love them all. Random Scrappy, controlled Scrappy, and Matchy Matchy. The random scrappy, done with darks and lights still needs a place to rest your eyes from all that business and randomness, so it has to be chosen and selected by the quiltmaker. A controlled scrappy offers that option by fabric selection (usually in the form of a "collection") . Matchy, matchy does it automatically , or should I say, by design. Your quilt is a beauty, and would be not matter which scrap method you chose because you have great talent which shines through in your work. Congrats on such lovely work!
