For those that prefer to do Entrelac in a rectangular, yet done in a circle formation, I’ve figured out the math to make it happen so it will match your desired afghan or throw sizes.

Visualize a granny square that is the size of your bed. What is wrong? Chances are the granny square matches one direction of your bed but is too short in the other because it’s a square. I’ve done this before guessing the chain length of an interior of an afghan hoping that each side grows proportionally for the bed so that no matter what you do or how big you make it, it will fit your bed perfectly.

Firstly, the Entrelac afghan I am suggesting is done in a continuous rotation around the centre point. The trick to the rectangular version is that you have to create the number of boxes in a row down the centre of the afghan instead of there just being one as you see in the colourful example. By creating the row first, your centre point is revolving around the entire row from the very beginning causing all sides to grow evenly around it.

Math Calculations

I used Bernat Super Value as my test. Using a 6 mm or size J crochet hook. It produced Entrelac boxes that were 2.75″ x 2.75″.

In my test, I realized it doesn’t matter what size yarn or hook I am using because what is important is the number of boxes needed to establish the centre row. As long as the proper number of boxes are in place in the centre point, it will grow properly.

Keep in mind that thicker, chunky yarn, will produce much bigger boxes which will make your afghans grow much faster. Obviously, if you use regular or thinner yarns, it will take longer to finish your project.

Starting Chain and Box Counts

Twin – 13 Boxes Across, Chain 130

Double – 7 Boxes Across, Chain 70

Queen – 8 Boxes Across, Chain 80

King – 2 Boxes Across, Chain 20

Throw – 4 Boxes Across, Chain 40

Lapghan – 4 Boxes Across, Chain 40

Once the first row is established, you will just rotate around the centre row as if it’s like the one square.

I will have tutorials coming in the future to demonstrate this and show you how to go around. For those who are familiar with Tunisian Entrelac, you will have a head start.
