Half Double Crochet Slip Stitch in the Back Loop Only Tutorial

Learn how to do the Half Double Crochet Slip Stitch in the Back Loop Only- one of my all-time favorite stitches! It’s a great alternative to a typical slip stitch. It’s also my favorite ribbing, and favorite crochet stitch that looks like it could be knit. And it’s really simple to do!

While this stitch is different than a typical Half Double Crochet or typical Slip Stitch – you’ll see why these two stitches combined make up the name! It also goes by “Yarn Over Slip Stitch.”

When to use the Half Double Crochet Slip Stitch (HdcSS)

The HdcSS is great for any time you need a stretchy fabric. It makes a dense but elastic fabric, which makes this stitch a perfect candidate for ribbing.

It can also be used for any time you want a knit-purl look without actually having to knit something! Just keep in mind that it really is very stretchy if you are using this stich for garments.

I used this stitch and others to create the beautiful texture in the Snow Drift Beanie, and to create a faux-knit ribbing in the Persephone Pullover.

Skills to Know

This is a quick stitch to learn, and is very beginner friendly! If you know how to slip stitch and half double crochet, you’ll pick it up quickly. If you are new to crochet or just need to brush up on the basics, click here for a beginner’s tutorial.


Grab any skein of yarn and your favorite hook to practice this stitch! I do recommend going up a hook size or two from what your yarn label recommends.

I’m using Lion Brand’s Hue + Me yarn in this tutorial in the color Desert. I absolutely adore this yarn – the colors are beautiful! It’s a Weight 5 wool and acrylic blend. (I used this yarn for the Hailey Headband!)

The Hue + Me yarn label recommends a size 6.5 mm hook – I’m using a 7.0mm hook for this tutorial. I highly recommend grabing a set of ergonomic hooks if you don’t have one already. Being able to easily go up or down a hook size to fit your project will change your crochet game! You can find my favorite affordable ergonomic hook set here.
