If you enjoy knitting toe up socks, top down hats or amigurumi figures, the disappearing circular cast on is an essential skill. This cast on feels almost magical because after working a couple rounds of knitting you simply pull the yarn tail and the cast on stitches are gathered tightly into a tiny circle at the center of your work. For those of you who also crochet, the disappearing circular cast on is similar to starting a crochet project with a magic ring.
I like to use a variation of the provisional cast on. Instead of casting on stitches around a piece of waste yarn, you actually cast on around the yarn tail.
