Designed this hat for my son for Pi Day - 2008. It is a toque-style so does not cover your ears unless you are an Elf or a Vulcan, in which case it will cover your ear tips!

I made this for my teapot which is a 6 cupper - it ACTUALLY holds 4.5 cups of water - just. It is about 4 inches high and 17 inches around.

The cozy uses about a half a skein of the lambs pride, and not much of the contrast color - I have not actually measured it - maybe 100 - 125 yards of mc and 50-60 yds of contrast.
