I gave myself a little experiment time with some new yarn and a crochet hook, and discovered that I can crochet in circles (or more accurately, spirals)! I'd always known it was possible, and had considered looking for a tutorial online a couple times... but it's always nice to figure something out on your own, even if it takes some time and requires a lot of learning from mistakes.
Here's my little circle.
As soon as I realized how easy it was to crochet circles, a whole slew of make-able round items came to mind. Hats, table cloths, tea cozies, hats... coffee cup cozies!!
Here's my coffee-cup-cozy-in-progress, which also works well as a Templeton-sized fez. I'll post a picture of the final product when it's done.
