Coffee (sleeve) anyone?

When I was cutting apart the shirts for Bargello Bowl I cut off all the cuffs. They kept reminding me of something and it finally clicked. I love my coffee extra hot and always ask for it to be made that way. Sometimes the cardboard sleeves don't really help all that much, but I gave this a try and I think it worked better. Maybe because it is a different medium to transfer heat thru? It's kind of cute too...guess I might have to carry one in my purse....once a girl scout, always a girl scout. :)
