Thanks again, all!
That quilt looks wonderful! I've been enjoying my hand piecing so far - it's not as quick as using a machine, but now I've figured out how to do a scant seam and my patches are measuring correctly, I'm finding that it's starting to come together more quickly now.
My only concern was one I thought of after I started - I'm not sure how a hand pieced quilt will hold up to washing. As I'm intending on making my project into a lap quilt, it will probably need to be washed on occasion..
