Just one last thought on the "go ahead" directions for my block. This isn't a double dog dare you, but go ahead and use my rounds to practice something/try something that maybe you always wanted to do but didn't want to commit to for a full quilt -- whatever that may be. Cute, complex, representational, abstract, textural -- is all good!
That's what I did for my center, I had some scraps I wanted to use, and a technique I wanted to use, and the time was now. So if mine comes to you and you want to work in blue or red or beige or whatever it is -- it is going to be great! Contrast as well as coordination is one of our quilter tools, and I think it is one of the most fun things in round robins.
