# Floss usage sampler

> Extrapolate skeins from a small sample stitched with your own fabric and tension.

- The page shows its formula, example, assumptions, rounding, and limitations beside the calculator.

## Formula and assumptions

The sampled cut length is multiplied by strands used, stitch-count ratio, and wastage allowance, then compared with the brand's strand and skein length. The ±20% range exposes uncertainty from stitch density, tails, and technique; it is not guaranteed coverage.

## Worked example

Example: if 100 stitches use a 100 cm cut with two strands, 1,000 stitches plus 10% need about 22 m of single-strand floss.

## 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.
