I loved Trif's answer, but being realistic I try to buy fabric at the quilting stores. Yes I like a bargin also but want to keep quilt stores from closing. Material has gone up to about $8.99 a yard. I still buy from them and also wait until they have a sale. My stash is huge and I still find new material. There must be some group for the quilting habit. I also send most out to be quilted. If I am feeling good I quilt myself but mostly pay someone else for it.
I just keep on quilting.
