I am guessing that you didn't look at the quilting before leaving the LA - lesson for everyone - check out what your quilter has done before you ever pay (you try on clothes before you buy don't you?). You absolutely have to take that quilt back and show her all the issues and request a refund. I certainly wouldn't give her another opportunity at your quilts until she can show you a much improved sample of her quilting. Then take the quilt home, rip out the stitching (it really won't take that long) and find someone who will give you quality work.
