I buy fabric on sale. Hobby Lobby has sale fabric all the time and my LQS usually has $4 or $5 a yard bolts of discontinued fabrics. I buy 1 to 3 yards of good pieces from those. I also buy fat quarters, jelly rolls, layer cakes, and charm squares. That has built up my stash. I am also bad about buying kits. I have many of those. I have made myself buy less this year. I'm finishing quilts instead of buying.
