Crochet cast on knit refers to the provisional cast-on method knitters borrow from crochet, using a waste-yarn chain and hook to create a removable starting edge. I use this exact method for toe-up sock knitting. This guide gives a quick reference.

Quick Steps
- Chain a loose foundation in waste yarn with a crochet hook.
- Switch to your knitting needle and working yarn.
- Knit through the back bump of each waste-yarn chain stitch.
- Continue knitting your project as normal.

Frequently asked questions
Why use crochet for a knitting cast on?
The crochet chain provides a removable foundation, letting knitters access live stitches later for a clean second edge, something a standard cast-on does not offer as easily.
