Do you ever wish you could work a stitch that’s a little bit taller than a treble, but a little bit shorter than a double treble? Let us introduce you to the wonders of extended and half stitches!

Both techniques are really quick and easy, and allow you to make any standard crochet stitch a little bit taller (extended) or a little bit shorter (half). The process of extending or halving involves only a small difference in how you work the stitch – the height of the finished stitch is only slightly different, but those differences add up across a piece of fabric and mean that you can create stitches of many more varying heights.

We’ll explain everything you need to know about making extended and half stitches by making a practice piece. Then you can try out your new skills by making our colourful wall hanging crochet pattern, or use your new stitches to make your own creations!

Why do I need extended and half stitches?

Adding any new technique to your crochet skillset will increase your versatility, but extended and half stitches are really easy and have loads of uses. Have a look at these two fabrics – both are made up of 15 stitches, but the final sloping row has been made with two different sets of stitches.

Example 1 The final row on this fabric has been made with 5 half trebles, 5 trebles and 5 double trebles. The slope is fairly gradual but you can see a definite step where there’s a change from the shorter to the taller stitch.

Example 2 The final row on this fabric has been made with 3 half trebles, 3 trebles, 3 extended trebles, 3 half double trebles and 3 double trebles. The slope is much more gradual and there’s no visible step.

Creating more gradual slopes is just one benefit of extended and half stitches, you can also use them to make shaping other increases and decreases in your fabric more gradual. The tiny differences between stitches can also be used to solve persistent issues with tension – for example, if you know you hook tightly, try working extended versions of the stitches in a pattern. Once you’ve learnt the simple techniques involved, you’ll find lots of ways to improve your crochet life by using these stitches.

One of the areas that causes the most confusion is what turning chains to use for half or extended stitches, but you can always use this handy chart.

To practice extended and half stitches, you can use any yarn you like and a hook in a suitable size for the yarn – whatever you feel most comfortable with. We used DK cotton yarn and a 4mm hook.

How to crochet extended stitches

Step 1

Start your practice piece with a couple of rows of treble stitches, to give your fabric a sturdy foundation – it will also give you a base row of ‘normal’ stitches to compare against your extended stitches. We worked 13 tr for two rows (ch15, tr in 4th ch from hook and in each ch to end, turn, ch3, tr in each tr across, turn).

Start the new row with a turning chain as usual – for extended stitches, just work the same number of turning chains as you would for the standard stitch that you’re adapting (there’s a handy table opposite). We’re going to make extended trebles, so you’d need 3 chains for the turning chain. If you were making an extended double treble, you’d need 4 chains, and so on.

Step 2

Now we’re going to make an extended treble. Start the stitch as usual for a treble by working yrh once.

Step 3

Insert the hook into the top of the next stitch as usual. Yrh and pull up a loop (you’ll now have 3 loops on hook).

Step 4

Next you need to yrh…

Step 5

…and pull through one loop only. This is the key part of the extended stitch technique and the extra ‘chain’ you make here is what lengthens the stitch a little bit.

Step 6

Finish the stitch as usual by working (yrh and pull through 2 loops)…

Step 7

… and then (yrh and pull through 2 loops) again.

Step 8

Repeat from Step 2 to make an extended treble in each stitch across. You’ll see how the stitch is just a little bit longer than a standard treble, with that extra ‘chain’ at the base of the stitch.

Step 9

If you wish, turn and work another row of extended trebles by repeating Steps 1-8. Alternatively, try making a row of other extended stitches, using the same technique. Here’s a row of extended double trebles, but you could also work extended triple trebles or extended double crochet stitches.

Recap To work extended stitches of any sort, just start each new row with a turning chain of the right length (see the table above. Begin each stitch with the same number of yrh as the standard stitch that you’re adapting (for example, for an extended double treble, yrh twice). Insert the hook as usual into the top of the next stitch, yrh and pull up a loop. Then yrh and pull through one loop only to extend the stitch. Finish the stitch as usual, working ‘yrh and pull through 2 loops’ as many times as you need to, until one loop remains. Work more stitches to complete the row.

How to crochet half stitches

Step 1

To practice half stitches, continue with your practice piece or start a new one.

If you start a new one, begin with a couple of rows of half double trebles. As with the extended trebles practice piece, if you made one, it will give your fabric a sturdy foundation and a base row of ‘normal’ stitches to compare your extended stitches with. Work 13 hdtr (ch15, hdtr in 4th ch from hook and in each ch to end, turn, ch3, hdtr in each tr across, turn).

Start the new row with a turning chain as usual – for half stitches, you need to work one chain less than the number of turning chains you would usually use for the standard stitch that you’re adjusting. So for a half double treble, you’d need 3 chains for the turning chain. For a half triple treble, you’d need 4 chains, and so on.

Step 2

Now we’ll make a half double treble. Start the stitch as usual for a double treble by working yrh twice.

Step 3

Insert the hook as usual into the top of the next stitch on the row below.

Step 4

Yrh and pull up a loop (you’ll now have 4 loops on hook).

Step 5

Continue the stitch as usual by working (yrh and pull through 2 loops) once (you’ll now have 3 loops on hook).

Step 6

Now that there are 3 loops on the hook, you need to work yrh…

Step 7

…and pull through 3 loops. This is the key part of the half stitch technique and finishes the stitch early, making it slightly shorter than a standard double treble.

Step 8

Repeat from Step 2 to make a half double treble in each stitch across. You’ll see how the stitch is just a bit shorter than a standard double treble, by missing out the final (yrh and pull through 2 loops) and pulling through 3 loops instead. You might also notice that this ‘halfing’ technique is like how we adapt a treble into a half treble.

Step 9

If you wish, turn and work another row of half double trebles by repeating Steps 1-8. Alternatively, try making rows of other half stitches, using the same technique.

Here’s a row of half triple trebles, but you could also work half quadruple trebles. Just start each row with a turning chain of the right length (see Step 1). Begin each stitch with the same number of yrh as the standard stitch that you’re adapting (for example, for a half triple treble, yrh 3 times). Insert the hook as usual into the top of the next stitch, yrh and pull up a loop. Continue the stitch as usual, working (yrh and pull through 2 loops) as many times as you need to, until 3 loops remain. Then work yrh and pull through 3 loops to finish the stitch early.
