Choose a reviewed construction and reconcile brim stretch, body count, depth and crown sections.

## 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. **Swatch flat and circular knitting separately** — Match the project’s knitting direction and stitch rhythm. Alternating knit and purl rows can produce a different gauge from knitting every round.
2. **Join a round without twisting** — Arrange the cast-on edge consistently around the needle before joining. Check the fabric edge itself, not only the flexible cable.
3. **Plan hat circumference and ease** — Use the intended head measurement and the pattern’s ease with a finished circular sample. Brim stretch and crown construction remain separate checks.
4. **Distribute crown decreases** — Choose a reviewed crown structure and map each decrease column. Calculate the count after every decrease round, then check the resulting height against row gauge.

## Try this example

A body count of 96 fits eight crown sectors of 12. Confirm the chosen finished circumference from the round swatch and reserve the crown’s measured depth before knitting the straight body.

## 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.
