Now I know that stash-busting does not necessarily mean scrappy, but for those for whom it MIGHT mean that, I just received the following link from the Quilt Inspiration blog. I've never seen this pattern before-- and apparently it's been around long enough that someone has an antique quilt made with this pattern. I like that it's a) simple (pattern is included, scroll down to the bottom); b) looks traditional enough for my tastes; c) is also "abstract" in that it conveys butterfly without being cutesy; and d) could also be made as non-scrappy.
