It's the simplicity of a granny square, but I decided to try something a bit different for this one. I'm using the crochet Brick Stitch to create the Crochet Modern Granny Afghan.
The original crochet modern granny has different corners than the updated ones.
In March 2025, we updated the modern granny pattern with crochet diagrams and a new approach for the corners.
I used Caron Cakes in the Cake Pop colorway for this project, but feel free to use any worsted-weight yarn in your favourite colours to create many fun looks. This would be an excellent pattern for your favourite sports team colours at those chilly games.
The original finished size is 52" x 64" using 6 Caron Cakes. If you want a baby version of 35" x 42", only 3 Cakes are needed. The updated pattern will not change the yarn quantity.

2024 Updated Version - Throw Size
I have multiple sizes going out so you can match the starting chain to be different sizes such as queen size, twin size and more sizes. Coming soon. I wrote this on Jan 5, 2024.
The 2017 version will get you a similar result, but I prefer not to slip stitch to a corner to start a new round. I would instead finish in a corner to start fresh in the next rnd. I use a single crochet to join to the top of the first st when double crochet is used.

Original Tutorial
Melanie says
I have tried new way to make a granny square blanket joining with hdc and sc at the end of a row. Tried this numerous times and used a 5mm hook. After the second row just beginning the stitches turn into a bowl shape. What's the problem here?
Mikey says
Hmmm I really cannot tell why that is happening based on words. That's really odd. I'm sorry, it's hard to know without seeing it. I would go back to the way you are used to doing corners if it helps you out but it shouldn't be bowling up.
Ray says
Could you send me a written pattern for the larksfoot granny afghan please? Thanks

What am I doing wrong, it's all wonky. ???
Mikey says
I saw this same photograph posted on social media with people offering suggestions. Have you tried just restretching the rectangle. We crochet in a round and tension causes this. What size hook did you use? It just may need to be stretched to realign.
