2 Different Ways to Seam Granny Squares Together

There are various methods to putting together or seaming a granny square blanket. The two that I will mention below are personally my favorite go to methods.

One of my favorite ways and most common ways in the crochet world is to crochet multiple granny squares and then seaming it together when you’re done. I love using the slip stitch method for this, but you can also use double crochet or there is also an invisible seaming method. It all comes down to personal preference.

You can also join as you go, which basically means that as your crocheting a granny square, you can go ahead and add another square to it. So instead of crocheting them one by one, you continue to add one as you go. I’ve also seen granny squares being made within the join as you go method!

I personally love the first method because you get to see which seaming method you like best for your crochet granny square blanket. For the Circle of Friends granny square, I decided on the slip stitch seaming method. So you basically take 2 squares, put them together, and then seam the sides by crocheting a slip stitch. Its creates a lovely, very noticeable border in between each square. Plus, you get two different crochet textures on the front and back of your blanket.

So to roundup our seaming methods.
