The product, in numbers.
The maths, without the maths.
Turning a crochet idea into a stitch-by-stitch pattern is fiddly and easy to get wrong.
Most tools are made for right-handers. Crochets works for left-handed crocheters from the start, and speaks US or UK terms.
Six things it does.
Yarn and stitch maths
Pick a project and a size and it works out the foundation chain, stitches per row, turning chains and the yarn to buy.
Sketch to written pattern
Tap stitches onto a grid and the written pattern comes from your squares, with a stitch count at the end of every row.
A preview before you start
One tap makes a labelled, computer-generated preview of the finished piece from your own chart.
US or UK terms
Choose once and every pattern, lesson and abbreviation follows it.
Left-handed from the start
Lessons come with left-handed videos, and charts and patterns follow your working direction.
For makers who sell
Pattern PDFs with your own logo and copyright line, a pricing tool and a sales log.
