The Klein bottle hat is done! The tube is smaller than the ones made at KleinBottle.com but it follows the same principle of being attached to the inner liner as a tube, essentially making the hat one-sided.
This past year I've discovered Alice Starmore's books. A friend of mine graciously offered for sale copies of books that I was interested in that were in the estate of a friend of his who had passed away instead of putting them on Ebay. He may not have received as much for them, but they will be put to very good use as I work at designing my own pieces.
