Zhillslady,
The lady that does my quilts charges by the sq. inch and I supply thread. She doesn't ask for the thread but I always take her some fresh spools. She can use them anyway she wants. Also, if I happen to pass that wonderful Dutch bakery I buy some goodies for her.

edited to add-of course I supply the batting and backing. My choice of backing goes with the colors of the quilt. How could anyone expect you to supply the batting and backing?
