Check the cuff both at rest and while passing over the heel before changing its length.

## Before you start

Use smooth, light yarn and a small sample that matches the lesson’s flat or circular construction. Mark the right side and record the starting stitch count. Follow the pattern’s own stitch key.

## How to do it

1. **Assess sock-cuff stretch** — Check the cuff over the widest point it must pass, as well as its resting fit. Test cast-on and bind-off limits independently from the rib fabric.
2. **Measure rib contraction and stretch** — Measure rib relaxed and under a defined gentle stretch. Use the state relevant to the finished opening, and check recovery after release.
3. **Choose a cast-on method** — Choose the edge by required stretch, appearance and whether stitches must be recovered later. Test the cast-on with the intended fabric.
4. **Calculate rows for a target length** — At 30 finished rows per 10 cm, 60 cm corresponds to 180 rows. Row gauge must be measured independently of stitch gauge.

## Try this example

Adding 3 cm at 40 rounds per 10 cm means twelve rounds. Preserve the cuff repeat and test cast-on stretch; twelve extra rounds do not fix a constricting opening.

## Check your result

- Count live stitches, trace one column and inspect both faces. Compare the relaxed edge with the middle of the sample before repeating the operation on a project.
- Stitch names and mounts vary between knitting styles. Follow the required fabric structure and pattern key rather than assuming every front loop is the correct entry point.
