post, I was having problems with this pillow. Nothing was lining up properly and I was getting puckers. I decided to keep going with it and quilt as recommended in the book (Dare to be Square).
It's a pretty puffy pillow so a lot of the puckering is masked. Especially since the quilting itself created some puckering. whoops! I haven't washed it yet. I'm not sure if I'm going to or not, but that would probably help even more.
I'm waiting for the sun to come out so I can take some pictures of this on the bed. Yay!
