Pinhole CO and How to Divide Your Stitches

The pinhole, disappearing, or invisible circular CO is primarily used for projects that are knit in the round and start with a small number of sts, usually 12 or less, like amigurumi, top down hats or toe-up socks. This type of cast on can be done with just your knitting needles, but if you find that too fidgety another option is to use a crochet hook. And the CO is even easier to manage if you use a crochet hook that has a knitting needle on the opposite end like the addi Duett hook & needle combo.
