I think this will never be a problem for me. I only buy fat quarters for smaller projects and applique pieces or to add a touch of variety in a quilt (like 2 or 3 for different patterns or colors to mix in). No way would I buy only only fat quarters to make a whole quilt out of them. There's just too much wastage that way. I buy yardage off the bolt for most of my projects. Locally non-sale priced fat quarters run around $3 each or $12/yd. That's about the same as premium quilting cloth. To me premium starts at around $10/yd. You can probably spend more if you want. The difference is a yard off the bolt will give you more material you can use because it isn't already cut into pieces.
