About the Simple HDC Blanket

When my in-laws were visiting over the summer, my MIL saw the Coco Throw which I made for my husband, and she 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 stitch. 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 any time 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. It is also a great beginner blanket pattern.

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 Yarn Hue and Me.

Even a thinner super bulky yarn 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’d like a more textured ribbed look, it is super easy to make that variation 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 with back loop only half double crochets.

Since it is super easy to adjust the width and length of this blanket, you create ribbing that runs either vertically (add more stitches and fewer rows) or horizontally (add more rows and fewer stitches).

ch(s): chain(s)
hdc(s): half double crochet(s)
sc(s): single crochet(s)
sl st: slip stitch


The ch 1 at the start of each row does not count as a stitch. Chaining 1 instead of 2 at the beginning of a half double crochet row is a matter of preference.

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.

If you’d like to adjust the width or length of the pattern simply add more stitches to the starting chain and then add more rows in multiples of 3s (so add a row for each block of color.)
