Materials & Tools For Granny Squares

To crochet granny squares and granny square shapes, you can use any size/mm crochet hook and yarn.

You can use any yarn fiber, like cotton, wool or acrylic yarn.

However, it’s most common to use either 3 light yarn (dk weight yarn) or 4 medium weight yarn (aran or worsted weight yarn).

Here are a couple of yarns I’d recommend to crochet granny squares:

These two yarns come in many beautiful colors & work for a range of granny square patterns.

Next, you’ll need a crochet hook that matches the yarn weight & a granny square blocking board is helpful when you block the finished pieces.

Best Tips for Crocheting Granny Squares

There are several factors that can help you have success when crocheting granny squares.

  1. Count stitches: Make sure you got each round right by counting stitches after finishing one round or side of the granny square.
  2. Weave in yarn tails as you crochet: Don’t leave weaving in yarn tails until you finish crocheting all your granny squares. Make a habit of weaving them in before you crochet another granny square, which will make weaving in ends less overwhelming.
  3. Use colors that contrasts well with each other. This will give you an overall more stunning look.
  4. Block your granny squares: Make sure you get a professional finish by blocking your granny squares.

Solving Issues with the Octagon Granny Square

Why does my octagon granny square start to curl & will not lay flat?

The octagon granny square has a tendency to start to curl and may be difficult to get to lay flat.
Start by trying to adjust the tension by using a bigger crochet hook, this may make it less prone to curl.
Another option is to try to reduce the number of chains between each double crochet cluster or omitting them altogether.
Then, make sure to block your granny square when finished.
