Compare shoulder width, armhole shape and sleeve-cap geometry together. A drop shoulder and a set-in sleeve use different seam paths and ease assumptions.

## 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.

## Try this example

Lay the proposed sleeve outline against the body armhole outline at equal scale. If their join lengths or shapes disagree, do not solve it by stretching one edge into place.

## 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.
