How to join crochet shapes together

Once you've made your crochet shapes, you need to join them together! Check out our tutorial which includes 5 different methods for joining your crochet.

How_to_join_crochet_shapes

Once you’ve mastered crochet shapes, there’s one final part of assembly that everyone dreads – joining your crochet shapes together! Fortunately there’s a few different methods, using either a yarn needle or a crochet hook, and all of which have their own individual qualities.

Counting stitches

One of the first stumbling blocks when joining crochet fabrics can be where to start. When you combine two pieces of crochet, your stitches are almost always going to be going in opposite directions (unless you’re joining into the sides of stitches). So for example, let’s say you’ve got two flat pieces of crochet and you want to start your join at one side, to start a join you would be working in the first stitch on one piece, and the last stitch on the other.

When it comes to shapes such as granny squares, it can get a bit more confusing as you have chains as well as stitches to join. Most commonly your corner spaces will be made from a 2ch, so if you’re joining two squares together you need to include one of those chains on each corner to ensure your join is the correct size (like in the diagram below). For joins it’s normally best to work into chains rather than around them, as this will help to keep your join straight.

Joining crochet shapes with a needle

As you’d image, you can treat your crochet much like you would treat any sewing fabric. That said though, there are a few methods that will help you to join your crochet shapes together perfectly and neatly.  You’ll need to start by attaching the yarn to your crochet. Here’s a simple way to do this

Step 1

Using a yarn needle and length of yarn, thread the needle through your first stitch on your right hand piece going from front to back (going under both loops of the stitch, or in the example below, through the corner chain of the side you want to join). Then thread your needle through the parallel/corresponding stitch on your left hand piece, taking the needle from the back to the front.

Step 2

Thread the needle back through the same stitch on the right hand piece in the same way as before, and then take your needle underneath the first needle stitch that you made (as in the picture below).

How_to_join_crochet_shapes_needle_start_02

Step 3

Bring your needle through the same stitch on the left hand piece, again going from back to front. By twisting your needle around the thread in step 2, you will now have what looks like a figure of 8 in your thread – this is what will help to lock it in place.

How_to_join_crochet_shapes_needle_start_03

Step 4

Pull tightly on your thread to finish your join (you may need to pull gently on both ends for it to close up neatly). Make sure you have enough yarn on your needle end to sew all of your join. You’re now ready to sew your shapes together using your preferred method.

Whip stitch join

If you’re not too bothered about neatness and just want your shapes joined together asap, then the whip stitch is the simplest and quickest way to join your crochet shapes. It’s easiest if you use a tapestry needle for this, but you can do it with a crochet too.

Please note – for the neatest results with whip stitch, you would normally do this on the wrong side of your crochet, however to make it easier for you to see where we are inserting our needle we have done this tutorial with joins on the right side.

To make your whip stitches less visible use the same colour yarn as on your crochet shapes, but we’ve used a contrasting yarn to make this tutorial easier to see.

Step 1

Attach your yarn to both shapes using the method above.

Working into the next stitch up from your join, thread your needle (front to back) under both loops of the stitch on the right piece of crochet, and then thread your needle (back to front) on the parallel/corresponding stitch on the left piece of crochet

How_to_join_crochet_shapes_whip_stitch_01

Step 2

Then just repeat, working into the next stitch on the right hand piece and then then corresponding stitch on the left hand piece, until you have joined your sides. You can finish off with the same method as we used to join the yarn in the first place, and then just weave in your ends.

How_to_join_crochet_shapes_whip_stitch_02

As you can see, whip stitch is a super-quick way of joining crochet shapes and is pretty simple when it comes to counting your stitches. However, it’s not the neatest method, and once you’ve finished, the join will be pretty solid – which is good for projects that you want to be sturdy and solid, but it’s not great for things like garments that might need a little bit of stretch.

Needle weave join

If you’re looking for a slightly neater needle join, and one that has a bit more give to it (important for if you’re making a garment that will need to stretch a bit), then weaving with your needle join is a good option.

Step 1

Start by joining your yarn to both pieces as in the method above. Then start by threading through the next stitch on the right hand piece and the corresponding stitch on the left hand piece, just the same as you would with a whip stitch.

How_to_join_crochet_shapes_weave_01

Step 2

Now thread your needle into the next stitch along on the left hand piece, taking the needle from front to back. We’ll then thread our needle back into the same place as the previous stitch on the right hand piece (needle going back to front)

How_to_join_crochet_shapes_weave_02

Step 3

Now, insert your needle (front to back) through the next stitch along on the right hand piece, and back into the same place as the previous stitch on the left hand piece (back to front).

How_to_join_crochet_shapes_weave_03

Step 4

Continue along repeating steps 2 and 3. This can get a bit confusing at times, but you can simplify it to thinking of it as:

Same place as last time on first shape, next stitch on first shape, same place as last time of second shape, go into next stitch on second shape.

If you’re still struggling to understand the sequence, this diagram might help.

Step 5

As you work along give your thread a pull from time to time, but not too tightly, remember that you want your crochet to sit naturally and have a bit of give to it. Once you have worked into both of your last stitches you can tie off your yarn and weave in your ends.

How_to_join_crochet_shapes_weave_05

As you can see above, by weaving your shapes together you get a much less obvious join, which should hopefully be a bit more flexible than a whip stitch. One downside of this join is that it can ruffle up your edges a little bit, meaning that if you’re making something to precise measurements it may take off some of your width.

Joining crochet shapes with a hook

If the idea of sewing all your crochet pieces together has you yawning with boredom already, fear not, you can always join your shapes with your crochet hook! It’s significantly quicker for us hooksters, and again there’s a couple of different techniques that you can use.

Slip Stitch Join

A bit like the whip-stitch method, slip stitch joins are a super-quick way to join two shapes together.

Step 1

Start by making a slip knot to attach the yarn to your hook. Insert your hook through the first stitch on your right crochet piece (under both loops, going front to back) and through the corresponding stitch on your left crochet piece (under both loops, going back to front). Then just slip stitch as normal – yarn round hook, pull through work and loop on hook.

How_to_join_crochet_shapes_slip_stitch_01

Step 2

Now just continue along, slip stitching the next stitches of both sides together. You may find it easy to almost ‘sandwich’ the pieces together so you can place your hook through both pieces in one go. Once you reach the end you can fasten off as normal

How_to_join_crochet_shapes_slip_stitch_02

And that’s how you do a quick slip stitch join. As we mentioned earlier, normally you would do your joins with the wrong side facing. Slip stitch joins tend to raise the fabric a bit where the join is, and slope to one side when the join is facing you, like in the image below.

How_to_join_crochet_shapes_slip_stitch_03

However the back of the join does look quite neat, with little horizontal lines like in the image below.

How_to_join_crochet_shapes_slip_stitch_04

Double crochet join

Double crochet joins are not only a nice way of joining shapes together but also add a nice decorative quality. As they’re more raised than our previous joins, they can create a nice waffle-like texture when used for joining granny squares. When doing a dc join, you would always do your join on the right side of your work.

Step 1

The best way to start a dc join is with what is called a standing stitch – basically you just go straight in and start with a dc, no need to slip stitch or ch1! So make a slipknot and put the yarn on your hook, insert your hook through the first stitch on your right crochet piece (under both loops, going front to back) and through the corresponding stitch on your left crochet piece (under both loops, going back to front), yarn over hook, pull through the work, yarn over, pull through both loops on your hook.

How_to_join_crochet_shapes_dc_join_01

Step 2

Continue dc stitching along until you’ve competed your join. Dc joins will ever so slightly lean to one side, so it’s important to remember to always do your joins going in the same direction for a neat final project (i.e. top to bottom or bottom to top).

How_to_join_crochet_shapes_dc_join_02

Again like the slip stitch join method the reverse of your join will look like little horizontal stitches.

How_to_join_crochet_shapes_dc_join_03

One of the reasons we love dc joins is that they’re easy to do and can be used to join a whole project very quickly. For example, let’s say you’re making a granny square blanket. You can easily join a number of squares together into vertical strips. Then when it comes to the horizontal joins, you would just work across up to your first vertical join, then you can simply ch1 which will take you over the join, then continue your horizontal join on the next square along.

Zipper join method

Although all of the above methods are fantastic for quick and easy joins, perhaps you fancy a super-neat join that works seamlessly with your crochet – well the zipper join method is perfect for this! It’s essentially a slip stitch join done slightly differently, and creates a join that is perfectly flat and doesn’t ruffle up your crochet at all. It can seem a bit tricky to start off with, but once you get the hang of it it’s sure to become your favourite way of joining crochet pieces together.

Step 1

Insert your hook (going front to back) in the BACK LOOP ONLY of the first stitch on your left hand piece of crochet

How_to_join_crochet_shapes_zipper_join_01

Step 2

Now insert your hook (again going front to back, you will need to twist your hook a bit to do this) in the BACK LOOP ONLY of the first stitch on your right hand piece of crochet

How_to_join_crochet_shapes_zipper_join_02

Step 3

Now yarn over hook. With this method it is important that when doing your yarn over that the yarn is coming from the back of the join.

How_to_join_crochet_shapes_zipper_join_03

Step 4

Then pull through the work and the loop on your hook (just like a normal slip stitch). That’s essentially all there is to it, but we’ll carry on with the next join.

How_to_join_crochet_shapes_zipper_join_04

Step 5

Insert your hook (going front to back) in the BACK LOOP ONLY of the next stitch on your left hand piece of crochet

How_to_join_crochet_shapes_zipper_join_05

Step 6

Now twist your hook to the front and (again going front to back) insert your hook in the BACK LOOP ONLY of the next stitch on your right hand piece of crochet. Make sure that your yarn is still at the BACK of your work – it’s quite easy to accidentally catch the yarn and bring it to the front, so you need to pay attention to this and may need to reposition the yarn as you do this step.

How_to_join_crochet_shapes_zipper_join_06

Step 7

Then just yarn round hook, pull through the work and through the loop on your hook like a normal slip stitch.

How_to_join_crochet_shapes_zipper_join_07

Step 8

Continue along to your last stitch and then fasten off. Once complete you can see why this join is called a zipper – because it looks like a nice little zip. This join will lie almost completely flat with your crochet pieces, and as it’s joined in the back loops only your crochet shapes will still have a nice defined edge and won’t ruffle up at all. Again like the dc join, when you come to horizontally joining shapes over vertical joins, you can simply ch1 to skip over the existing horizontal join.

How_to_join_crochet_shapes_zipper_join_08

With all of these joins these guides are just as a reference. You can do any of these joins going from top to bottom or vice versa, and if you’re left-handed then you may find it easier to start your joins in the opposite crochet piece to the ones we’ve started in. However you choose do do your crochet joins, the most important thing is to remember to be consistent in the direction of your joins for a neat result.
