We have been playing around with this block in our 9P project. It turns out beautifully no matter the fabric. I have links to the blocks being made on our activities page-

I think Dagny did this with a 9P for one of her tops. I know GrammaNancy has some examples with her blocks, also quilt queen 2 did some and I did some in flannel. I wish I had somemore of that flannel would have made a great guy's quilt.
