Julia, it's the WOW background in the
top that's the problem, not the backing fabric. But now that you mention it, my Kaffe quilt with the white backing has no show-through either. That never occurred to me.
SewBizGirl, you may have a point. I'll try that and see how it looks.
This is the pattern :

BTW Julia, it looks like we're neighbors! I was just in Waterford the other day, visiting The Little Quilt Shop. Cute little store!
