Thanks for the tips. I didn't happen to have any borders on this quilt...just big blocks. It was square when I loaded it...I didn't know about pinning or sewing the sides. How do you re-square a quilted quilt? I do use my walking foot putting on the binding. I do pin the binding - I didn't measure or check to see if each side was squared....it looked curvy, but after putting on the binding it was definitely wavy.
