How to work Half Double Crochet (UK Half Trebles)

half trebles (UK) also known as half double crochet (US) is my favourite stitch. It combines the tightness of  double crochet (UK) (single crochet US) and the speed of treble stitches (UK) (double crochet US) and forms a nice thick fabric suitable for winter garments and blankets.

It's a nice speedy way of building a crochet fabric without too many holes and gaps

Instructions for half double crochet

First make a length of chain


wrap the yarn around the needle


Insert the hook into the third chain from the hook. Be sure to have 2 threads of the chain stitch above and 1 underneath the hook.


wrap the yarn around the needle again


Pull the yarn through the chain


You should have three loops on your hook. Hook the yarn up again and pull it through all threes atitches


You have made your first stitch.


repeat the process in the next chain to make your second stitch


Then all along the row into every chain


make 3 chain and then turn your work around. This is called the turning chain


The 3 chain counts as a stitch so do not work into the first stitch otherwise you will have too many stitches and your work will get wider and wider with more and more stitches. So miss one stitch and work into the next stitch


Coninue all along the row, remembering that the turning chain counts as a stitch, so when you get to the end of each row, work one half double crochet into the top of the turning chain


You will find that there are little holes along the side edge where you have missed a stitch. Some people don't like this so they do not count the turning chain as a stitch. Instead, they work into the first stitch and then do not work into the turning chain


This however leaves a wavy edge. It is up to you which method you prefer
