I think the cathedral window effect really adds something.

I have done four of the 10 minute blocks but my instructions said to use 5 layer cakes (10") size. Love it!

I like the larger ones

Good Job.. I like the larger one. A customer of mine made 4 queen size quilts using that block with sashing's between the blocks, I quilted all of them, it was a lot of fun, and the block looked fun to make, although I have not made one yet..
