My baby brother is a math geek. Don't get me wrong, I'm a math geek too, but he's way, way, way more of a math geek than I am. So, when trying to figure out what to give him for his birthday, I happened upon pictures of a Klein bottle hat. For those who don't know what a Klein bottle is, you should go and wrap your head around this. And then you can come back and see the Klein bottle wrap itself around my brother's head.
Here is the hat after all the knitting and end-hiding was done. Hiding those ends was made a bit complicated because I didn't think far enough ahead to realize that it would be hard to reach my hand in the narrow ends of that tube. What you can't see is that there is a slit in the green decrease stripe to allow the other side of the hat to pass through. An imperfect representation of a four-dimensional object, but you work with what you've got.
This shows the hat folded in on itself, but before grafting the two skinny ends of the tube together. So far, it doesn't look like something anyone in their right mind would wear! The real challenge is coming up, as grafting k1, p1 ribbing is not something I've done before.
Here is the finished hat. It's impressively warm - two layers of worsted weight wool will do that - and nice and stretchy. The loopy part on top can be worn flipped down so that it's not so dorky looking. I'm pretty happy with how it came out, especially since I didn't use a pattern.
And finally, my brother modeling his new hat. Don't worry about him being too hot wearing it in the house - since his head is both inside and outside the hat at the same time, he can never really overheat in it. In fact, he might want to consider wearing a real hat under it when he goes outside so he won't catch a cold...
