Quiltgranny

Hi Everyone,

A while back someone else on this forum made this topper using this wonderful pattern, "Table Scraps" from the magazine "Quilt", Apr/May 2011 issue.

I made the top of it up this evening, paying close attention to the 1/4" seam and other accuracies... but find it won't lay flat. I even tried to press it into submission, including using starch. Still, it just wants to ripple a little here and there.

This is my first Dresden plate pattern. Can anyone tell me what caused this and how I can fix it?

Thanks so much,
