The only perfect person died many years ago.
So relax, good enough is good enough. Do you think your little man will peer at the stitching and drool out that it isn't perfect?
No, he'll love it because Grandma made it for him.
Relax, some peoples, Indians and Amish and Mennonites (I think) deliberately put in one wrong thing so they won't be perfect in anything.
So sew and enjoy it. Show it off and let us see it too. Take pictures of the baby with the finished quilt, and let us see the darling enjoying his "blankie".
