I save my odd socks or ones with holes for rags. Turn them inside out, and they are great for dusting. Wash, dry, reuse. If I use it for a really icky cleaning job, I toss it.laundry basket of mismatched socks
That's what I do. I save the odd ones when some get holey, and then I still have a pair of socks.I did start buying 6 pairs all the same when I was working.
