I usually buy batting on a roll and with a business license on wholesale basis and sell it at retail price comparable to stores in the area. I have 80/20 and Dream Poly.
My forms request Name, address, phone# Date.
Date Due, Quilt name/description, size, Quilting pattern, color of thread.
It has quilting Cost per Sq in, Cost of batting per yd.
also offer: make binding, attach binding, hand sew binding. price per linear in.
Do you want is trimmed? I always give back all the trimmings even the tiny scraps.
I also have them sign and date when they pick up the quilt. (sometimes they have a friend pick up)
I have had good results with all of my questions. If they bring their own batting that is what I use, no questions.
