Just let me show you some of my crochet cozies. I find it's really funny to cover different objects with a warm crochet yarn "coat". With these cozies, a simple glass bottle or a can of soda can become pretty and special objects to decorate your home.
Here you are the cozy can
The cozy flower vase
More cozies for these simple but cute little glass bottles
They look really nice with flowers or... hooks in them ;-)
