Gray Ombre half double crochet blanket draped on a chair

When my in laws were visiting over the summer, my MIL saw the Coco Throw which I made for my husband and asked if I like gray.


She commented that she likes gray too and I filed that info away. I knew I wanted to make them a blanket, I knew it needed to have gray, and I knew it needed to be somewhat of a simple pattern because….

crocheting blankets can be boring!

Are you with me?

The finished product is worth all the effort, but sometimes, in the middle of it, when it seems like a blanket will never come to an end, it is really hard to remember that!

Enter the perfect stitch: the half double crochet. It is so simple and rhythmic and the fabric it creates is perfect for a soft and squishy throw.

This is the kind of crochet project you can pick up at anytime and work a row or two. It can be your between WIPs project. Or you can plow through it and finish it quicker than you’ll believe.

Knowing that this blanket was headed to my sweet in-laws also help propel me to the finish line! We made sure to fill it with grandkiddo cuddles before boxing it up and shipping it out to them!

What yarn should be used for the Simple Half Double Crochet Blanket?

Using a bulky category 5 yarn makes this simple throw fast, soft and squishy! Unfortunately the Big Twist Chunky Yarn that I used has been discontinued.

Some other good options would be Premier Serenity Chunky or Lion Brand’s Color Me Easy. I haven’t work with either of those yarns but their look and composition are similar.

Even a thinner super bulky would work nicely. If you decide to use a thicker super bulky yarn, going up in hook size would be a good idea to keep that great drape of the blanket.

Please make sure to make your own gauge swatch to determine how much yarn you’ll need for your blanket.

What if I want a ribbed half double crochet blanket?

Go find a different pattern. I am totally kidding! If you like a more textured ribbed look, it is super easy to make that happen with this pattern! Simply work into the back loop only of each half double crochet.

You can see the difference in texture created in the Easy Crochet Baby Blanket which is done in back loop only half double crochets.

If you need a little help on where to place the sc for the border, check out the images in the Easy Baby Blanket post for guidance.

You can also start this blanket with a foundation half double crochet (fhdc) instead of a foundation chain. You’ll want to fhdc 127 then start the instructions below at Row 2.

  1. Ive made many hats and scarves using the Hdc ribbing. So simple and yet such an interesting effect.My most recent was a bedcover for one of my grandsons in his university colors. I know he will be surprised and delighted.

  2. I’ve made several baby blankets using this simple pattern. They came out beautifully and were admired by all. Great pattern.

  3. Working on a ribbed hdc blanket in black with variegated purple stripes for my daughter… and sweaters for the grandkids, of course… lol. And yes, at the same time 🙂
