"Crochet Casserole Coasters":
Also known as pot-holders... hot pads... trivets... practically anything but "casserole coasters", actually.
(And just what kind of casserole is this person preparing to make, anyway? I see broccoli, green onions, carrots, tomatoes, bell peppers, eggs, and macaroni... Remind me to have a previous engagement, should they invite me over for supper.)
