I just love my state. Show your Colorado love with the custom-made crochet bottle cozy. The logo for the Colorado flag is cut out of felt (made of recycled plastic - of course!) and applied to a hand crocheted cozy made of acrylic yarn. Acrylic's better for the beer, you see. It's machine washable, won't stretch out, and is 100% guaranteed to keep your beer nice and cozy.
This cozy also fits a can, in case that's your sort of thing.
