Crochet designers, you’re in the right place.

If you want clear, accurate, beautifully written patterns your customers will love, my tech editing services are here to help.

Imagine buying a pattern and finding that the stitch counts don’t work or the row numbers don’t add up. Small errors like this can turn a beautiful pattern into a frustrating experience – and they’re almost impossible to spot in your own work.

That’s why every crochet pattern deserves a professional tech edit before it’s published.

How I can help you:

As a certified crochet tech editor, I will work through your pattern line by line to:

  • Check mathematical accuracy, stitch counts, repeats, and grading
  • Proofread for spelling, grammar, and consistency
  • Review formatting, charts, images, and abbreviations
  • Ensure your pattern style, voice, and structure stay true to you

Together, we’ll make sure your pattern is polished, professional, and ready to delight your customers.

“Crocheters deserve to have clear, accurate and beautifully written patterns every time.”

  • Certified Crochet Tech Editor (Cool Wool School)
  • Experienced crochet designer and crocheter
  • University degree in English Language
  • Background in accountancy for precision and accuracy with numbers
  • Passionate about detail – with a supportive, collaborative approach

I’ll never tell you what’s “wrong” – I’ll suggest improvements, explain why, and work alongside you to achieve a finished pattern you’re proud to share.

What others have said

I asked Gemma to tech edit a crochet tote bag pattern I had designed a while ago that needed refreshing ahead of a relaunch. Gemma was very clear with her suggestions and comments and had a real eye for the details. It’s amazing what a fresh pair of eyes can find! I highly recommend Gemma for any crochet tech editing needs, and I look forward to working with her again in the future. Thank you for your speed and precision Gemma!

Lauren, Manatee Squares

“Gemma is my absolute go to for tech editing my crochet patterns. I love how she doesn’t try to change my style and layout. She is very meticulous with checking for typos and inconsistencies throughout the pattern and also offers great suggestions. I am so bad at checking my work so it always brings me peace of mind when using Gemma for my tech edits. 100% recommended!”
