This Koozy pattern can be used on a number of things, plastic water bottles, aluminum cans, bottles of multiple types of beverages, etc.
It can also stretch slightly if the water bottle is one that is a little bit wider.

Being made of cotton means that any “sweat” or condensation would be soaked up just like a cotton coaster would do.

Yarn: Any worsted weight cotton yarn will work, I typically use Lily Sugar ‘n Cream when I work with cotton, they are 3 oz skeins and I usually go into a second one slightly.

Tension/Hook size: I crochet tight, and use a g hook, if you crochet loose, you may want to go down a size or two depending on how loose you generally make your stitches. However you do it, as long as it fits the beverage container you are working the pattern for.
