Granny Square tutorial

The granny square is one of the most classic and beloved crochet patterns—and it’s just as popular today as it was generations ago. In this tutorial, I’ll show you how to crochet a multicolour granny square, changing yarn colours after each round to create a vibrant and modern look. Below you’ll find the written granny square pattern, a step-by-step photo tutorial for beginners, and a video tutorial.

Looking for a single-colour Granny Square Pattern?

This tutorial shows you how to crochet a multicolour Granny Square, changing yarn colour after each round. If you prefer a simpler look, I also have a single-colour granny square tutorial  that uses the same basic method but works the entire square in one colour. It’s a great option for beginners or for projects where you want a more uniform look.

Notes on the Granny Square

  • The pattern recommends turning your work over after each round – it keeps the square even and makes the blanket reversible.
  • Each round is worked into the chain spaces between the treble clusters of the previous round.
  • The Granny Square uses treble clusters (groups of 3 UK treble stitches).
  • The pattern uses 2 chains for each corner space. You can experiment with 1 or 3 chains if you prefer a tighter or more open corner.
