I had a quilt basted by a LAer and didn't specifiy exactly how I wanted it done as I thought she was the professional and would know better than I. When I got it back it was just sewn in horizontal rows 10 inches apart with "relaxed" fabric between the lines.
I just had to pull all the basting lines out and do it myself.
It just goes to show you need to get a clear indication of what they will do.
Now I use my narrow table and do the centre first, then each end.
Good luck with it.
