The major difference ... Well, it's crocheted, that's it. I have no doubt it would fit on a can just as well as a glass. Make them up with the sweet holly design for Christmas party events, or forget the holiday and make them in a variety of colors for whatever event you might feel like. I know, you didn't need me to tell you that.
So, should you be interested in crocheting up a set (or two ... they'd make great gifts) here's the pattern. (If you want to print, click to enlarge and then copy/paste it to a word document, where you can save or print).
Thanks for dropping by,
