I can guarantee that we have all been there. Before I took things all apart I would try releasing the stitches that lapped over and caused the pucker. Many times that helps then following the same sewing line give it a bit of a stretch. Now always but sometimes this works.. Starting from the middle of your quilt (this pattern)go diagonal from end to end and work outward. I have to tell you I am an experienced quilter and I just made a charity quilt that I had this problem with. In many instances I had to take out the entire row. I was not a happy quilter to have to do all that frog stitching.I am sure no matter what you do or don't do it will be well received because of all the effort you put into making this special gift. What your eye sees will not be seen by others. Only the love will be seen and with great joy.
