A perfectly classy quilted cork can koozie for your cooled beverages.
They can be stored flat or upright. It fits snug, but not too snug to be an issue getting on your can. Best to put it on while the can is closed though.
Cork is naturally water resistant, so no wet fingers when your drink sweats, and there is an insulated liner in between the cork to help keep it cool.
Your coozie may have small brown dots on the inside. That is from burning the ends of the threads to keep them secure as you continue to use your koozie and so that the outside didn't have to have lots of bulk back-stitching areas. Those parts aren't very pretty, but they keep the outside pretty and are hidden when in use.
