I recently got a king size batt at 50% off. It is big enough to be cut for 3 or more toddler/baby quilts, depending on their size. Our guild has a book library - they can be checked out for a month or two at a time. It also has a donation table, I get fabrics and magazines from that. I read the magazines and then take them back for the next person. They do have a money donation box for the items on the table - I try to put in a dollar or 2 when I get fabrics.
Cut back where you can and are willing to sacrifice - I'll discontinue cable before I'll give up quilting.
