Free crochet stitch tutorial: The Sonic Stitch

Today I’m posting something a little different on the blog- a crochet stitch tutorial!

A couple of weeks ago I was playing around with some scrap yarn I had found after doing a bit of a tidy up of my yarn stash and came up with this textured stitch combo!

It kind of looks like sound waves so I’ve named it ‘The Sonic Stitch’! (I also really like using alliterations 😉)

I’d love to use this stitch to make a blanket- I think it’d work great! Perhaps it’s something I’ll do in the future, but for now I thought I’d just post the stitch repeat 🙂

If you make anything using this tutorial, I’d love to see it! Be sure to tag me or use the hashtags #thesonicstitch or #crafty_cc

You’ll need:

– Yarn of your choice 
I’ve used Aran weight/ 10 ply yarn in my swatch.

– Corresponding crochet hook
I’ve used a 4.5mm hook.

– Yarn needle

– Scissors


This pattern uses US terminology

  • WS wrong side
  • RS right side
  • rep repeat
  • ch chain
  • sc single crochet
  • dc double crochet
  • fptr front post treble crochet

Pattern notes:

  • To create the stitch effect, I’ve used the same colour for all odd rounds- I refer to it as the ‘main colour’ in the pattern. I’m using Paintbox Yarns Cotton Aran in Paper White (601).
  • The chains at the beginning of the rows do not count as sts.

Changing colours:

You’ll need to change colours after each row; this is done in the last stitch of the previous row.

To do this: pull your new yarn through the final 2 loops to complete the stitch.

Single crochet:

Double crochet:
