Stupid thought- it's saving all those fabric items from the garbage heap either way! Besides, it's keeping the thrift store alive by showing a demand for the used items, meaning it will still be in business when the poor people need it. It's dumb to classify what you will use that fabric item for.
I confess to buying thrift store curtains to make a Halloween costume- as curtains they weren't very good because of some runners and wear spots, but the fabric has a new life whenever my daughter wears her Hakama.
