Joining Granny Squares With Single Crochet (Back of Loop)

In this post, we'll be showing you how to join your granny squares using the single crochet stitch in the back loop only.

By working in the back loop only, you create a ridge that runs along the top of your seam, adding beautiful detail to your finished blanket.

This method is easy to learn and creates a strong and durable seam that will hold up well over time.

So, grab your hook and some yarn, and let's get started!

1: Arrange Your Squares

Before joining your granny squares together, it's important to arrange them in the pattern you want them to be in. 

This will help you keep track of where you are in the project and ensure that the finished blanket looks the way you want it to.

To arrange your squares, you can lay them out on a flat surface such as a table or the floor. Experiment with different arrangements until you find the one you like best.

By taking the time to arrange your squares before joining them, you can avoid mistakes and ensure that your finished blanket is exactly what you had in mind.

2: Choose Your Joining Yarn 

When choosing the yarn you want to use for joining granny squares with single crochet, you have a few options. 

You can use the same color yarn as the squares, or choose a contrasting color to make the seams stand out.

Depending on the pattern, you may be asked to use the same yarn weight and hook size as your granny squares so that the seams lay flat and the finished blanket has an even appearance.

But don't shy away from experimenting with another yarn weight and hook size to achieve the look you want for your creation, like we did with our lacy daisy granny square blanket.  

For this project, we used chunky yarn and a 9 mm hook for the squares but joined them with a yarn weight half the thickness of the squares and a 5.5 mm hook. 

The end result was a lovely looking single crochet join that sits in the ditch between the squares rather than being chunky and raised.

3: Join Your Squares 

Joining your granny squares together requires patience and attention to detail. 

To ensure that your seams are neat and even, it's important to follow a methodical approach. 

Here's how to join your squares using the single crochet stitch in the back loop only:

Step 1 - Start by picking up your first two granny squares and lay them on top of each other with the right sides facing out. Make a slip knot in your yarn and secure it onto your hook.

Step 2 - Insert your hook into the corner of the granny squares from front to back, yarn over your hook, and pull through to make a slip stitch.

Then insert your hook back into the same corner, from back to front, and make a single crochet.

Step 3 - Next, insert your hook into the back loops of the next two corresponding stitches from front to back.

Yarn over your hook and pull up a loop, then yarn over again and pull through both loops to make a single crochet.

Step 4 - Continue in this way, working single crochet stitches in the back loop only along each side of the squares until you reach the next corner.

When you reach the next corner space, work a single crochet stitch into the corner stitch.

Step 5 - Then, pick up two more squares and work a single crochet into the corner stitch of the second square.

Continue to make single crochets in the back loops to join more squares as you go.

Step 6 - When you reach the end of the seam for the column, make a chain 1, and cut your yarn leaving a tail of a few inches.

Pull the tail through the loop on your hook to secure the stitch. You have now joined two columns together.

Step 7 - Repeat the steps above to attach the third column to the second column, and so on, until you've joined all the columns.

Remember to have the right sides of the squares facing out.

Step 8 - Once you've joined all the columns, repeat the process to join the rows together.

However, when you get to a corner join, don't make a single crochet in the join, instead chain 3, skip over the join and continue working in the back loops.

4: Finish off

Once you have completed all the joins, use a daring needle to weave in the loose ends.
