I finally got around to writing up the pattern for the Scooter Scarf!
My scooterist had been asking for a scarf that would be warm and extra long for wrapping around multiple times - 7 feet was asked of me, and with double knitting... I only made it 6 feet.
It's a simple pattern based on double knitting. The explanation of double knitting in the "Son of a Stitch and Bitch" book is really helpful.
