The October Hat by Sloane Rosenthal for our Year of Hats features a provisional tubular cast on. This cast on creates a really lovely, stretchy edge that is reminiscent of a commercial or machine knit.

I created a video showing how to work the cast on, as many people have had questions about the first few steps and exactly when to use the working yarn versus the main hat yarn.
Although this cast on requires a few extra steps, it creates a really beautiful finish and is totally worth the extra effort!
