Give it your gauge and size, and it writes a blanket, scarf, amigurumi ball, beanie or granny square blanket row by row, with the stitch count at the end of every line. Switch between US and UK terms at any time: US single crochet (sc) is UK double crochet (dc).

- Stitch and row counts are rounded to the nearest whole number from your gauge over 4" (10 cm).
- Turning chains: sc ch 1 and hdc ch 2 do not count as stitches; dc ch 3 counts as the first dc.
- Gauge is measured after blocking, in the same stitch the pattern uses.

Good to know
Which turning chains does the generator use?
In rows, single crochet uses ch 1 and half double crochet ch 2, and neither counts as a stitch. Double crochet uses ch 3, which counts as the first stitch. In joined rounds the starting chain never counts as a stitch (ch 1 for sc, ch 2 for hdc and dc). Patterns from other designers can use different conventions.
How does the amigurumi ball work?
It starts with 6 single crochet in a magic ring and adds 6 stitches every round until the widest round is close to pi times the diameter at your gauge. Even rounds fill the middle, then the decreases mirror the increases back down to 6 stitches.
How is the beanie sized?
Hat circumference is your head circumference minus the negative ease you choose (2" by default). The crown is a flat circle that grows until it has the stitches for that circumference; it should measure about circumference ÷ pi across. Even rounds then bring the hat to your chosen height.
What are UK crochet terms?
The same stitches with names shifted by one: US single crochet is UK double crochet, US half double is UK half treble and US double is UK treble. Slip stitch is ss in UK patterns and skip is miss.
Does it work out yarn amounts?
Yes, from your own swatch, never from a guess. Yarn use depends on fiber, weight, hook and tension, so the generator asks how much yarn went into your 4" × 4" gauge swatch (or one granny square), as a length or a weight with the skein label. It scales that by the area of your project, adds 10% for ends and joining, and shows yards, meters and skeins.
