This is the wildest knitting I've ever done! You used a long cable needle (about 4 feet long!) twist it around itself and make a moebius strip, some sort of mathematical thing with only one edge...when you knit you knit from the center outwards, it is wild to see it grow that way! I got the pattern and technique from books by Cat Bordhi. This is the book I used. I plan to make a moebius felted bowl from it next!
