How to create crochet patterns means turning your own design idea into written instructions other crocheters can follow, using standard abbreviations, stitch counts, and repeat notation. I wrote my first pattern for other people after years of only designing for myself, and the hardest adjustment was writing clearly enough that a stranger with no access to my head could actually follow along. This guide covers the notation basics, the process of writing the pattern itself, and the math for resizing it to a different gauge or size.
Understanding Pattern Notation
Written patterns rely on a few consistent conventions: abbreviations like sc and dc for stitch names, a number in parentheses at the end of a row showing the expected total stitch count, and asterisks marking a section that repeats. For example, *sc in next 2 sts, 2 sc in next st* repeat around (24) means repeat the starred instruction around the full round, ending with 24 total stitches.
Rather than repeating the full abbreviation glossary here, link your own written pattern back to a general crochet abbreviations reference so readers unfamiliar with a specific term can look it up without you having to define everything inline.
Step-by-Step: Writing Your Pattern
- Make the item once yourself first, taking notes on every stitch and round as you go, rather than trying to write instructions from memory afterward.
- Convert your notes into standard abbreviations and repeat notation, checking each row’s stitch count as you write it.
- Have a test crocheter, ideally someone unfamiliar with your original process, follow the written pattern exactly and flag anything unclear.
- Revise based on their feedback, paying special attention to any step where they had to guess your intent.
- Add a materials list, gauge note, and finished size at the top before publishing.
Resizing a Pattern
Start with a gauge swatch in both your original yarn and the new yarn or hook size, measuring stitches and rows per 4 inches for each. Divide your target new measurement by your new gauge to calculate the stitch count needed, then round to the nearest multiple your stitch pattern requires, since many textured stitches only work in specific stitch-count multiples.
I always recheck my swatch gauge partway through a resized project, since tension can shift slightly once you are working a larger piece rather than a small test square.
Frequently asked questions
What does the number in parentheses mean at the end of a row?
The number in parentheses is a stitch-count check, telling you exactly how many stitches you should have after completing that row or round. If your actual count does not match, you have likely missed or added a stitch somewhere earlier in the row.
How do I make a pattern bigger without changing the stitch pattern?
Switching to a larger hook size with the same yarn increases your gauge and finished size without altering the stitch pattern itself. This is usually simpler than recalculating stitch counts, though it works best for modest size changes rather than a dramatically different finished size.
Need the abbreviation reference first?
Writing clear notation gets much easier once the standard abbreviations feel familiar.
