Check out GreenFairy's blog. She has a quilt she just finished that will knock your socks off! Saw it last night and still can't stop thinking about it.
I think you have a beautiful quilt that you are making for your sister, I hope she likes it, but if she doesn't you can give it to me. LOL I know she will love it. Great job.
Very nice job designing this quilt. Your sister will love it! The change in the 2nd picture is really nice. Love the addition of the blue to the corners.
