Fit the shell repeat and edge stitches, then estimate yarn from that exact textured sample.

## Before you start

Gather the measurements, counts or timing sample needed below. Record their units and whether they describe a sample, the whole project or one purchased package. Use a finished sample when dimensions or material use depend on fabric structure.

## How to do it

1. **Fit shell and fan repeats** — Count the base stitches consumed by one repeat, including skipped stitches. Add edge instructions once, not once per repeat.
2. **Measure a foundation chain** — A chain alone does not establish the finished width. Work several rows into it and measure the relaxed fabric instead.
3. **Make a representative crochet swatch** — Sample the actual stitch pattern, working direction and finishing method. A plain-stitch square cannot establish the gauge of a textured or mesh project.
4. **Estimate yarn from a crochet rectangle** — Scale the sample’s yarn use by area only when the project uses the same structure and finishing. Budget borders and denser sections separately.

## Try this example

For a six-stitch repeat plus two edges, ten repeats require 62 base stitches. Measure their finished width rather than assuming the chain width equals the throw width.

## Check your result

- Recheck the inputs against the actual sample or label, keep units consistent and round only the final count or purchase. Repeat a sample if a small measuring difference changes the decision.
- These arithmetic examples assume the measured structure stays comparable. Shaping, borders, dense textures and color changes require their own allowances or samples.

## [Stitch-repeat fitting planner](https://threadcabin.com/tools/stitch-repeat-fitting)

Find the nearest stitch counts that preserve a pattern repeat and edge stitches.

A repeat is the sequence worked again; edge stitches sit outside it. Enter the fixed edge count per side.  Compare the lower and higher valid totals with their predicted widths and deliberately select the fit you want. A valid multiple alone does not establish a comfortable size.

Fixed edge stitches are removed first; the remaining count is rounded down and up to complete repeats. The optional gauge converts both valid counts to finished measurements so their size difference is visible.

- Target stitch count: 62
- Stitches per repeat: 6
- Edge stitches per side: 1
- Target width: 20 cm
- Gauge stitches: 20
- Gauge measurement: 10 cm
