Gosh, I am overwhelmed by the amount of attention this quilt is getting. You are all so generous in your comments.
To answer some of the questions -
Suse - It took about a week to organize the scraps, but that was because I took them with me on a trip to visit the kids. At home it might have taken longer because there would have been other (more interesting) things to do.
butterflywing - If you sort the fabrics into darks and lights before starting to piece the quilt, it's easier to make the decision as to which is which. There are a few fabrics that are filling both roles in this quilt. And although a block may not look well separated into dark and light when you view it alone, when you see the same block in a big quilt it looks fine.
judee0624 - about 6 weeks from start to finish, not working on it every day because it was so hot here for part of that time.
everyone - thanks for the compliments on my color sense, but really that isn't necessary in a true scrap quilt. I took everything I had, mixed it all together with total abandon, and didn't stress about color at all. The more fabrics you use, the less you have to worry about what goes together. It's very freeing.
