This is a sketchy layout of a quilt I'm working on, with nothing sewn together yet. At this point it looks better viewed in thumbnail form:

The curves, of course, will look smoother once it's sewn together -- but also, the optical illusion will work better when I have a bunch more fabrics representing more tints and shades. If you happen to have any scraps of quilters' cotton you want to contribute, in saturated colors and relatively monochromatic, I'd appreciate them. Anything that's at least 3.5 inches is useful.
