Wavy edges
I was careful to square up a recently quilted baby quilt before adding the binding. I was also careful not to stretch the binding as I sewed it on. But now with the binding on and sewn on both sides, the edges of the quilt ripple. Does this mean I need to "block" the quilt? (I'm not sure how to do this) Should I add more quilting to the outer border? What will flatten it?
