Working increases in crochet is very simple, and vital if you want to be able to create different shapes, either flat or 3D ones. Here, we’ll show you how to use increases to make the fabric slope at an angle.

Working increases will shape the fabric outwards and are especially useful when working in the round. You can use increases to work flat shapes in rows or rounds, such as squares or flowers, or to create 3D shapes worked in the round.

How do I increase double crochet stitches?

In US terminology ‘How do I increase single crochet stitches?’

Increasing one double crochet stitch is very simple – you just work two double crochet stitches into the same stitch on the previous row, increasing the stitch count by one.

You can work this increase anywhere along the row, but if you work the increase in the centre of the row, this will create a different effect to increasing at the start or end of the row. Increases worked on every row will create a different effect to increases worked on every other row.

To practise increasing, first make a short chain (around 10-12 chains) and work 2-3 rows of double crochet. Then practise making increases, at various points on the row, to see the shaping effects.

Step 1

Work a dc stitch as usual: insert hook into next stitch, yrh, pull yarn through, yrh, pull yarn through 2 loops on hook. Then begin another dc, inserting hook into the same stitch as the one just worked.

What else do I need to know?

You can create all sorts of shapes using increasing and decreasing

Now that you’ve learnt how to increase your stitches, the next step is decreasing – check out our guide on How to decrease in crochet stitches

Your pattern should tell you what sort of increase or decrease to work, and where. There are a few things to remember though…

  1. If you’re shaping at a specific point on every row, you may find it helpful to use a stitch marker to mark this point on every row.
  2. If you’re working dc increases or decreases at the start of a row, work the one turning chain as usual, then work your increase in the first stitch, or your decrease over the first two stitches. For a triangle shape, decrease at the start or end of every row.
  3. If you’re working in the round to create a circle shape, work the increases evenly on every round.
  4. To make a square shape in the round, you’ll need to work a 3dc increase to create the corners.
