How to use planned pooling for crochet colourwork

What is planned pooling in crochet and how does it work? We have all you need to know about this popular new colourwork technique!


We all love the vibrancy that variegated yarns can bring to a crochet project, but you can also use them to create effects such as argyle-style patterns that have a fascinating woven look. The technique is known as yarn pooling, planned pooling or colour pooling. We’ve seen some fantastic examples of it cropping up online lately, so we dug a little deeper to find out exactly how it works.


The technique involves intentionally working the colours of a multi-coloured ball of yarn in a specific way, to create a design or colour effect when you crochet. The technique is done with an easy formula and works with almost any variegated yarn, which means you can get an argyle look without having to cut the yarn for each colour.


Crochet designer Ann Mancini-Williams of explains just what you need to know, and guides you step-by-step through the process of making her impressive argyle scarf. The hook size required may depend on the yarn you choose. With planned pooling, the tension was 15sts and 13 rows to 10x10cm. Once you’ve figured out tension and the colour sequence aspect, it’s chains and double crochet stitches all the way. This project is fantastic for developing your skills.


Planned pooling suggested yarns

Planned pooling requires very particular kinds of variegated yarn and we thought the experts might be able to help us track them down. We asked Wool Warehouse to share their wisdom on suitable yarns they have in stock. They told us: “We did some research on colour pooling a little while ago, and found that the following yarns seem to be popular for this technique.”

Many variegated yarns will work, but self-striping yarn will not work. When looking for a yarn, the yarn must have an even number of colour sequences. For example, if the yarn has 15cm of blue, 10cm of white and 5cm of purple then every repeat of those colours must be 15cm of blue, 10cm of white and 5cm of purple – these are referred to as the colour sequences. The individual colours within a sequence do not have to be the same lengths, but the whole colour sequences do.

You also want the colours in each sequence to be no less than 7.5cm long and no more than 30cm long. For our scarf, we used 2 skeins of Caron Simply Soft Camo (100% acrylic, 113g/186m) in Red Camo.

To start

Use any hook size you want for planned pooling – start by using the size recommended on the ball band and see how you get on. The key aspect to this technique is tension – there are tips and tricks on this later to help you succeed.


Step 1

Start by pulling a good length of the yarn out of the ball to determine what the colour sequence of the yarn is. It doesn’t matter if the yarn is pulled from the centre or the outside of the ball – the technique will still work, but the colours will be in a different order. The colour sequence in this yarn is Grey, Red, Black, Red.


Step 2

Now it’s time to crochet! Start at the beginning of your yarn – it doesn’t have to be a specific place, you’ll see why later. Start chaining evenly until you have chained through one entire colour sequence. For our example, we decided to end at Red, so our colour sequence for the foundation chain is Black, Red, Grey, Red.


Step 3

The LAST loop on your hook MUST be the first colour in your NEXT colour sequence. In this example, Black is the beginning of my NEXT colour sequence.


Step 4

Start crocheting your first row of pattern stitches as follows: dc in fourth ch from hook, *ch1, skip next ch, dc in next ch; repeat from * across, until you have worked through one entire colour sequence.


Step 5

At the end of your last dc, the loop on your hook MUST be the first colour in your NEXT colour sequence. You will have chains left over from your starting foundation chain but don’t worry, you won’t need to use these leftover chains so you can just undo them at the end.


Step 6

Now for the important step. Before you turn to work the second row, you need to REMOVE one set of stitches: you will need to pull out the last dc and ch1 you made at the end of Row 1. This is where the magic happens, as you will now have shifted the colours by one set of stitches. You will only need to do this once, at the end of Row 1.


Step 7

Now you can continue working the moss stitch pattern for Row 2 and each row as follows: ch2, dc in first ch-1 sp, *ch1, skip next dc, dc in next ch-1 sp; repeat from * across, placing last dc in last turning ch-sp. The colours should shift by one stitch to the right on the row you are working on.


Step 8

As you crochet each row, pay very close attention to your colours. When you turn, the colours will still shift to the right and since it is the opposite side, that is what will make the colours criss-cross. To keep track of this, have a look at the dc below and to the left of the dc you’ve just worked.
