You cannot quilt through the Heat & Bond that you used. I tried it once and it was a operation in frustration. The needle got all gummed up and thread broke a lot, after 4" I gave up.

Looks good to me. With the design in that gorgeous fabric, no one is going to notice that it is not quilted. I have been making some of these boxes & they are quite addictive & so darn cute.
