Welcome to my 7 and 7/8ths world. :-) Follow the link below to find 27" x 27", 100% cotton bandanas at $2.50 each.
Copy and paste the link to your address bar and it should take you right to their website and the correct page.
They have become my hat of choice, floaties strainer, brow mop, emergency bandage/sling, lifesaver (hunter orange), last resort tinder, dustmask, cooling "rag", glasses wiper, flag to gain assistance, pot grabber and oh yes as a handkerchief! :-)
Party On ! 2010
