I made a baby quilt for my niece. I washed it but didn't check it out before I gave it to her. It did the exact same thing. I zigzagged over the area really densely and it looked and worked fine after that. Usually I don't wash my quilts before i give them away. Now I am going to. I live in Oregon -- my niece in Texas. I had to take it home and fix it and mail it back to her. Small price to pay for fixing a blunder.
