I have a few times. I go to Goodwill & buy 100% cotton Men's shirts. I am picky about the fabric. I have also bought some 100% cotton sheets. It can be challenging to find the tag on the sheets so when I can't I go by feel. I have been fooled a few times & got sheets that had some poly in 'em. Those are good for straining the fruit when I am making jelly so not a total waste.
