I am having a long arm quilter friend baste my next queen quilt using water soluble thread. We have talked about it, and she is going to do a 3 or 4" all over grid with a 12-14 stitch per inch. She was a bit nervous about getting the tension right since she hadn't used the thread before, but I reminded her it didn't really matter since it would all go away! I just need it to stay in long enough to quilt on my sit down machine. Yes, I know lots of you pin baste big quilts quite successfully, but I absolutely hate it. She is going to charge me half of what she charges for a simple loose pantogram which makes both of us happy.
