Not going to lie. When I first saw the need for a half double crochet stitch on a pattern I decided to just use a double crochet. It didn't exactly work out.
Good news, this is an easy stitch and if you alraady know how to double crochet, it's in the bag. For those of you who don't need the pictorial, I'm not going to have you sifting through this post trying to find a quick answer... The only thing that is different between the double crochet and the half double is the fact that you take off all three loops on the first pass. That is seriously it.
If you need to see what I'm talking about, check out the tutorial below:
First chain as many as you want your piece to be long and add two extra chains to the end.
Yarn over, push through the "vee" of the chain two down from your hook and yarn over again.
Pull through the first loop on your hook. You will have three loops on your hook at this point. Yarn over and pull through all three loops on the hook.
Yarn over, push through "vee", yarn over, pull through all three loops. Repeat.
Take your half double crochets all the way down your chain. When you reach the end, chain twice. These two chains will act as your first half double crochet. Turn your piece so that you are again crocheting right to left.
Continue until you reach your desired length! Happy Sunday, Dreamers :)
