How to Join Granny Squares (3 Ways)

the 3 methods of joining granny squares shown on a white table next to a row already joined together

You’ve just made a bunch of granny squares…now how do you connect them? In this tutorial I’ll be showing how to join granny squares three different ways.

The whip stitch is my preferred way of joining granny squares and I show two slightly different ways to create different looks. You can also join granny squares together by using a crochet hook, which creates a textured border and can be used with a contrasting color for a fun design choice.

Once you figure out which method you want to use to join your granny squares, there are many fun things you can make! I used a whip stitch to join granny squares when making my Agnes Sweater Vest and I love to make granny square tote bags and zipper pouches. It’s s great way to use up scrap yarn and turn them into something functional!

In case you missed it, I have a tutorial for How To Crochet a Granny Square with written and video instructions to get you started!

Below is a a table of contents so you can skip around this tutorial as needed.

Whip Stitch – Method 1

The first method is a called a whip stitch and uses a tapestry needle and yarn to join together. This is the same way I joined my granny squares together for my Agnes Sweater Vest and I like how it makes a flat join between the squares.

Step 1: Thread Needle

Thread your needle with coordinating yarn with enough length to go across the side. Using the yarn, measure out two or three times the length of the side and that should be enough length.

Or, if you left a long tail after finishing your granny squares, then you can use that to join two squares together!

Step 2: Place Squares Together & Make First Stitch

Starting by placing two squares wrong sides together and line up the corners and stitches along the side you’ll be joining together.

Insert the needle into the first stitch at the corner (through both stitches of the ‘v’) of the square facing you – it will be in the chain 1 space between the two clusters of double crochets. Then continue to put the needle into the corresponding corner stitch (through both stitches of the ‘v’) of the square held behind.

Tie a knot to secure the yarn and then bring the tails over so that you can whip stitch over the tails in the next step.

Step 3: Sew Across

Insert the needle into the second stitch, under both stitches of the ‘v’ into the front square and then into the corresponding stitch of the square behind. Then bring the yarn towards you over the side of the squares.

Insert the needle into the third stitch of the front square and the corresponding stitch of the back square.

Repeat these steps, connecting the squares by inserting the needle through each chain 1 stitch, until you reach the corner.

Step 4: Finish & Weave In Ends

At the corner, I like to thread the needle under the loop made on the last stitch to secure. You can make another knot if you want it extra secure.

Then thread the yarn through the stitches on the wrong side of the squares and cut yarn – you’ve joined two granny squares together!

Whip Stitch – Method 2

This whip stitch method is very similar to the first method but it creates a pattern, like a border, around the squares. The stitching used to join the squares is also a little more discreet.

Step 1: Thread Needle

Start by threading your needle with coordinating yarn with enough length to go across the side. Using the yarn, measure out two or three times the length of the side and that should be enough length.

Or, if you left a long tail after finishing your granny squares, then you can use that to join two squares together!

Step 2: Place Squares Together & Make First Stitch

Bring two granny squares right sides together (different than the first method!) and line up the corresponding corners and stitches on the side you’ll be joining together.

Find the chain 1 stitch at the corner and insert the needle into just the outside stitches (instead of through both stitches of the ‘v’ like the first method).

Secure with a knot before moving onto the next steps.

Step 3: Sew Across

Insert the needle into the next outside stitches of the granny square in front and the corresponding stitch of the granny square in back. Bring the yarn towards you over the side and then insert the needle into the next stitches.

Repeat these steps until you the reach the end!

Step 4: Finish & Weave In Ends

When making the last stitch at the corner, thread the yarn through the loop made to make a knot. Pull on the tail yarn to tighten and make another knot to make it extra secure.

Thread the tail yarn through the stitches in the back (like shown in first method) and cut yarn.

You’ve joined two granny squares together! There should be two lines, like a border, between the granny squares since the yarn was only brought through the outside stitches.

Crochet Method – Slip Stitch

The last method uses a crochet hook and a slip stitch to join two granny squares together. This method creates a raised texture and is a good option if you want to use a contrasting yarn to connect your squares for a different design element. It does take more yarn this way so make sure you have plenty to connect all the squares in your project.

Step 1: Place Squares Together & Set Up

Put two granny squares right sides together, and line up the corresponding corners and stitches on the side you’ll be joining together.

Insert the hook through the chain 1 stitch right at the corner and loop the working yarn over the crochet hook. Yarn over and bring the yarn through the loop on the hook and bring up a loop.

Step 2: Crochet Across

Insert the hook into the second stitch (I bring the tail yarns over so that I can crochet over them for the next few stitches) and bring up a loop. Yarn over and pull the yarn through both loops on the hook.

Continue with slip stitches across the side, inserting the hook into each chain 1 stitch until you reach the next corner.

Step 3: Finish & Weave In Ends

After making the last stitch, cut yarn and pull the tail all the way through and pull tight.

And you’re done!
