I have had my eye on this quilt also, it is so striking. I think we should both do it. No 'Y' seams!
My biggest worry is not the piecing, but the quilting.
If you scroll down the pictures in the link you can see where they have laid the quilt on the ground near the water. I cringe just thinking about such a beautiful quilt on the dirty/wet ground.
Go for it! What fun!
