Plan a shell-stitch throw
Fit the shell repeat and edge stitches, then estimate yarn from that exact textured sample.

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
- Fit shell and fan repeats — Count the base stitches consumed by one repeat, including skipped stitches. Add edge instructions once, not once per repeat.
- Measure a foundation chain — A chain alone does not establish the finished width. Work several rows into it and measure the relaxed fabric instead.
- 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.
- 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
Find the nearest stitch counts that preserve a pattern repeat and edge stitches.
Before you use this tool
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.
Method and limits
Formula and assumptions
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.
Worked example
Example: target 103 with an 8-stitch repeat and 2 stitches at each edge gives nearby valid counts of 100 and 108.
Limits and rounding
Results are planning estimates from the values entered. Displayed decimals are rounded for craft use; whole materials and repeats round up where the method says so. Confirm gauge, material behavior, construction, and finished measurements before committing supplies.
