Fabric lines come and go so fast. I'll go to the LQS and see some new fabric that I know by the time I finish my current project will not be there. True some else will be, but if I really like a fabric I buy it when I see it so I do get to work with it. That's how I have built up a stash. Then there's yardage or fat quarters I need like staples you keep in a kitchen that are part of my stash. My stash also has complete projects yet to completed. Last but no least, if there's a sale there's a reason to go to the LQS which always results in a purchase.
