That's what they called it in the 1970's issue of Sunset's "Gifts You Can Make". Basically it's just two half circles sewn into a cone (one for outside, one for lining). Pretty easy, but I tried to butch it up a bit by sewing down the "pixie" point of the cone and using a tan canvas. Added bonus, I also found out that Sam stays sitting still if you photograph him while sipping OJ!
Here it is again form the back, rotated 90 degrees so the points face a different direction. You can see the basic shape. Easy, right?!! I want to try to make it again, probably a little bigger. I might even try a really big one for me (pixie point intact? Hmmm....)
