Samhain,
It's 6'x4' thin cotton in a Celtic Dragon print. It's actually a tapestry I bought at a RenFest to keep the rain off my glasses. Worked great for that! I also used to wear it in the summer canoeing and hikiing but it was getting too beat up by branches and stuff.
It was great though. With that much fabric it was easy to tie up like a tarp to make a nice patch of shade during a lunch stop. While canoeing I'd wet it down and let evaporative cooling keep me comfortable.
Not sure if I'd wear it to a mall though.
