Excellent brioche grafting tutorial: https://www.interweave.com/article/knitting/learn-to-graf...

Knit 44” then grafted per second link. First attempt using this grafting technique. The instructions are very clear, well-explained, and well-paced. I still managed to fuck it up in the first pass by pulling too tightly. Still, I’d argue this is the best join so far. Will definitely try again.
