Flour Sack Towels as Flats

Has anyone here used flour sack towels as flats? If so can you please share your experience? I'm genuinely considering having a stash of 36 flour sack towels, 5 or so one size covers, and 6 or so one size all in ones for babysitters and such. I don't want to stock up on flour sack towels If in reality they work like crap as flats. I've been watching/reading reviews and people seem to like them as flats but I figured I'd ask here because I feel people will be more honest about their experience.
