How To: Circumference of crochet hats

Have you ever wanted to make a crochet hat without a pattern, but didn't know when to stop increasing? Here's a helpful formula I learned from someone at CGOA (Crochet Guild of America).

First, measure around the person's head. Let's say their head measures 22" around.

Next, divide the circumference by 3.14.

Example: 22 / 3.14 = 7

That means that when your circle reaches 7", stop increasing and work even until you reach the desired depth.

Happy crocheting! :->
