Sounds like you're doing fine, then. "Pretty and flat" are always good! :)
I loved that quilt top - but I made the mistake of trying to quilt it with my embroidery machine. ARGHHHHHH - never again! No matter how I propped up the weight, the hoop kept falling out of alignment. And my (terrible, nasty, awful, useless) Futura refused to follow its own centering marks, so many of the quilting designs ended up way off-center. :? Plus, something went goofy with the tensions in the middle of the quilt and all the designs ended up with crazy amounts of the top thread on the back side of the quilt.
I keep saying that someday, I'm going to make that quilt again - it was so cheerful and nostalgic with the vintage prints.
