How to Join Crocheted Granny Squares Using A Double Crochet Stitch
Joining Granny Squares with a UK Double Crochet
In this article I will be explaining how to join your granny squares with a double crochet stitch. I will use text, photographs and a video to help you.
I will be using UK crochet terminology throughout and I will provide an equivalent table for those who use other crochet terminology.
There is an assumption in this article that you have made at least four granny squares to be joined and you know how to do a slip stitch, a double crochet and a treble crochet.
Using a double crochet is one of the easiest joining methods for your granny squares.
I would recommend that you join single granny squares together until you have enough in a row for the width of your make. Once you have two complete rows I would then join the rows together.
Joining Single Granny Squares
In the photos I have provided I have chosen to lay my granny squares to be joined one under the other. This is so you can see more easily where to put your hook. You can start yours the same way or hold your first two granny squares together which is how I would normally start.
Make a slip knot on your hook leaving about a six inch tail. Hold your first two granny squares together.
It is very important that your granny squares have the same number of rows. This is because in order for this joining method to work you will be working the same stitches on both sides e.g the first stitch you will push your hook through is the second corner chain on the right of the granny square closest to you and then push your hook through through the same stitch in the granny square held on the back (see image 1).
Once you have both stitches on your hook, complete the double crochet stitch by putting your yarn over your hook and pull through both stitches. You should now have two stitches on your hook then put your yarn over your hook again and pull through the last two stitches. You have completed your first joining double crochet.
I'm going to emphasize again the importance of making sure you are going through the same stitches in both of the granny squares you are joining. If you don't then when you get to the end you will be left with one side longer than the other.
Your next double crochet will be made in the stitches immediately next to the one you have just made. You will see in image 2 that this will be through the stitch that sits on top of the first treble cluster. Image 6 shows you what a treble cluster is.
Once you have identified the next stitches to pick up and have your hook pushed through them, complete your next double crochet. Repeat this action in every stitch along the row, being careful to match stitch for stitch on your two granny squares until you have joined the stitch above the last treble of the last treble cluster.
The final stitch is now worked in the first chain of the 2 chain corner on the left hand side of your granny squares. See image 3.
Cut your yarn leaving about a 6 inch tail and pull through the last stitch on your hook to secure. If you have more granny squares to join I would leave the tails - as they are very handy for when you join rows of granny squares to each other.
Joining your Granny squares in Rows
There is a small difference between joining single granny squares together and joining rows of granny squares. The difference is when you come to where a cross-way of four granny squares are to be joined. You will need to make a slip stitch where the two vertical double crochet joining ridges meet (see image 7). Do this by inserting your hook under the first double crochet stitch on one side and repeat for the opposite side so you have two stitches on your hook. Then pass the back stitch over the front stitch and off your hook. You will then carry on joining the row with double crochets until the next cross-way and repeat this step for each one.
All of your yarn tails can be easily hidden under the double crochet stitches. (See image 8).
Image 9 shows you a completed cross-way of four granny squares.
You will notice that this method of joining granny squares with a double crochet leaves a raised ridge effect on the joins (see image 4) and on the back it leaves a flat stitched effect, (see image 5).
The raised ridge can be a feature of your crochet make and can look very attractive in a contrasting colour on blankets and bags. However the choice of which side you like best is yours, there is no right or wrong way.
There are a few different ways to join your granny squares. You can use; a flat braid join, a slip stitch join, a whip stitch join, a reverse mattress stitch join, join as you go and a double crochet join - to name a few.
