Quick answer: The cable cast on uses your knitting needles to create new stitches by inserting between existing stitches — no long tail needed. It produces a firm, rope-like edge.
What it is
The cable cast on is worked directly from the needle, creating stitches by knitting between the last two cast-on stitches and placing each new stitch back on the left needle. It gives a sturdy, defined edge with a rope-like appearance, and it doesn't require estimating a tail — making it great for adding stitches mid-row or at the beginning of a row.
When to use it
- Adding stitches at the beginning of a row (buttonbands, short-row shaping)
- When you want a firm, stable edge — buttonhole edges, pocket openings
- When you're out of tail yarn and need to add stitches mid-project
How to do it
- Start with a slip knot on the left needle. Knit into it and place the new stitch back on the left needle — you now have 2 stitches.
- For each additional stitch: insert the right needle between the last two stitches on the left needle (not through a stitch — between them).
- Wrap the working yarn around the right needle as a regular knit stitch.
- Draw the loop through and place it on the left needle by twisting the right needle tip toward you.
- Repeat steps 2–4 for each stitch needed.
Common mistakes
- Inserting the needle through a stitch instead of between stitches — always go between after the first two
- Twisting the new stitch when placing it back on the left needle — the right leg should sit at the front
- Casting on too tightly — the edge won't be flexible
