Great Job! It looks perfect!
I think the name of the pattern is actually "mock cathedral". I haven't googled it to check. I don't use any "batting" at all, I just use the fabric circles to make a lighter-weight coverlet. In Texas it's a great "quilt-alternative" for those summer babies!

PS: I personally think the real cathedral is easier - I HATE marking the square stitch lines on the circles...it's hard for me to make perfect.
