How disappointing!!!!
It is a quilt that you are going to keep for yourself???
I would probably rip it all out. It may take a while but if you don't, every time you look at that quilt you will be unhappy about the quilting done on it.
I wouldn't send anything to her again. You may want to eventually mention the puckers to her so she knows why you are not going to have her quilt for you again!
