Striped Shells Glass Cozy - free pattern

I made this design a few years ago, for our livelihood project. Now we are going to make it again...so I made some samples and took pictures.
This is easy to make, and would fit several shapes and sizes of glasses since it could stretch a bit. The addition of a stripe makes it more attractive, but you can also skip the stripe and crochet continuously in one color.
