Granny squares are a timeless staple in the world of crochet, loved for their versatility, charm, and endless design possibilities. 

But if you’ve ever finished a stack of beautifully crafted afghan squares, only to be stumped about how to join them together, you’re not alone. 

The joining process can make or break the look and feel of your project, whether it’s a cozy blanket, a vibrant scarf, or a unique garment.

In this post, we’ll dive into various techniques on how to join crochet squares, from simple and invisible methods to decorative joins that add an extra layer of flair. 

These tips and tricks on how to join crochet granny squares will help you elevate your projects to the next level. So grab your crochet hook, gather your squares, and let’s explore the best ways to bring your creations together seamlessly!

How to join crochet squares with yarn needle

There are plenty of methods on how to join your squares with the yarn needle. We will explore two different methods.

1. Whip stitch 

The whip stitch is a straightforward method of joining your crochet work that lets you create a secure and polished join.

That makes it a favorite among crocheters for projects like blankets and cushions.

Whip stitch is a great choice for different stitch counts for squares with different numbers of stitches on the edge.

First thing, lay your squares flat with the right side (the side you want to show) facing each other. This ensures the seam will be on the back or the wrong side of your work.

Cut a length of yarn and thread it onto your yarn needle.

Insert your needle into the first corner stitch on both squares. Pull the yarn through, leaving a short tail for weaving in later.

Insert the needle into the next stitch on both squares from the same direction, pulling the yarn snug.

Repeat this process, moving from stitch to stitch along the edge.

The most important thing is to be consistent with the direction (always sewing from front to back or back to front) to maintain uniformity. It will make a huge difference.

For best results avoid pulling too tightly, as it can distort the edges of the squares.

When you reach the end of the seam, secure the yarn with a small knot. Then weave in the loose ends on the back side of your work with your needle.

2. Mattress stitch 

The mattress stitch is a favorite for its clean and professional results, making it perfect for showcasing the beauty of your granny squares.

Once mastered, this technique will become a go-to for all your crochet projects!

The mattress stitch is a great way to join granny squares seamlessly.

It creates a nearly invisible join while allowing the squares to lay flat, making it an excellent choice for projects where appearance matters, like blankets or garments.

Place your granny squares next to each other with their right sides facing up.

Ensure the edges you’re joining are aligned perfectly and the number of stitches match.

Cut a length of yarn, thread it onto your tapestry needle, and secure the end with a knot or leave a short tail for weaving in later.

Look at the edges of the granny squares. Each stitch has two loops at the top: the front loops (closer to you) and the back loops (farther from you). You’ll be working with the joining part of the loops.

Insert the needle under join of the loops on one square, then under the join of loops of the corresponding stitch on the other square.

Pull the yarn through, but don’t pull too tightly—leave a little slack to allow for adjustment.

Move to the next stitch on each square, always picking up the join of loops.

Pull the yarn snugly but gently after every few stitches to ensure the seam stays tight and even.

Once you’ve stitched a few inches, gently tug the working yarn to close the seam.

The stitches will disappear into the join, creating a smooth and nearly invisible seam. It is a great choice for sewing seams on garments and accessories too.

Avoid pulling the stitches too tightly to prevent puckering.

How to join crochet squares with a crochet hook

1. Slip stitch method

The slip stitch method is a versatile and straightforward technique that combines function and style, making it a great option for joining granny squares seamlessly.

Provides a strong, durable seam with a little texture perfect for beautiful blankets and other frequently used items.

This easy join creates a flat and slightly raised seam, adding a decorative join to your project while keeping it sturdy.

Place your granny squares wrong sides together if you want the slip stitch join to show as a ridge on the right side.

For a flatter join hidden at the back of your work, place them right sides together instead. 

Insert your crochet hook into the corner space or stitch of both squares (the first stitch where you’ll begin the join). Pull the yarn through both stitches to create a slip knot on your hook.

Insert hook into the next stitch of the first square and the corresponding stitch of the second square. Work the squares together using the slip stitch.

You can change the look and finish of this method by working through back loop only of the square near you and front loop only of the square further away from you.

Yarn over and pull through all loops on the hook to complete the slip stitches.

Repeat this process across the edge, moving from stitch to stitch on both squares.

2. How to join crochet squares using single crochet stitch

The single crochet stitch join combines functionality and beauty, making it a go-to technique for many crocheters. It results in a clean, secure, and professional-looking finish.

It’s perfect for projects like blankets, bags, or garments where durability and a stylish finish are desired.

Place the granny squares wrong sides together for a raised, decorative seam on the right side.

For a flatter join, place the squares right sides together so the seam sits on the back.

Insert your crochet hook into the corner stitch of both squares.

Pull the yarn through both stitches and make a slip knot on your hook to secure it.

Yarn over and pull up a loop through both squares.

Yarn over again and pull through both loops on your hook to complete the single crochet stitch. Continue working single crochet stitches into each pair of stitches from both squares.

You can change the look and finish of this method by working through back loop only of the square near you and front loop only of the square further away from you.

Alternatively, work through the front loop of the first square near you and back loop of the square away from you for the seam to be hidden at the back.

This technique allows the single crochet stitches to sit a bit flatter between the two squares.

The flat braid join is a stunning and versatile method for joining granny squares, creating a lacy and decorative seam.

This technique is perfect for projects like blankets, shawls, or table runners where the join itself is a part of the design.

The flat braid join is more time-intensive than some methods, but the beautiful results are worth the effort.

Once mastered, it can transform a simple project into a true showstopper!

The lacy braid adds an elegant, polished look to any project.

Works well with any square design or project size.

Tips for Success:

• Keep Chains Even: Consistent chain lengths ensure a uniform braid.
• Check Alignment: Double-check that the squares are aligned properly before joining.
• Experiment with Colors: Use a contrasting yarn to make the braid a standout feature or matching yarn for subtle elegance.
