Paliscat (or bipolarbear, as she's known in the AT community) tells us about another way she uses these handy carpet squares after the jump. I also use them as trivets for warm things like serving bowls you don't want to sit on a table without protection.
FLOR provides six 6" sample swatches for only $5. Order up and tell us how you you use them.
Thanks for tagging your door mat pic with "apartmenttherapy," bipolarbear. Double thanks for the great DIY idea!
