This hobby is an expensive one. You alwys need to buy something. It is not cheap to make a quilt.
Check out your local thrift stores or garage sales and craigs list for fabric. Some quilt shops have clearance sales at the end ofthe year and have fabric for $4 a yard. Buy 99 cent Fat Q's from Joann's use coupons for them and Hancock fabrics.
Buy when you see a sale and build up your stash!!!!
