Half-Double Crochet Spike Stitch: Step-by-Step Tutorial

The half-double crochet spike stitch, also known as the HDC spike stitch, is a versatile and textured crochet stitch that adds depth and interest to your projects. This stitch has gained popularity among crocheters due to its unique appearance and the ability to create various patterns.

The Half-double crochet spike stitch (hdc spike)is worked by inserting the hook into a stitch one or more rows below the current row, yarning over, and completing a half-double crochet stitch. The more rows you skip, the taller the spike stitch will be.

This technique creates elongated stitches that "spike" into the fabric, resulting in a textured and visually appealing design.

Unlike regular crochet stitches that are worked into the stitches of the previous row, the HDC spike stitch allows you to create patterns and designs that span multiple rows. This opens up a world of possibilities for creating intricate and eye-catching projects.

The HDC spike stitch is perfect for adding a decorative touch to blankets, scarves, hats, and other accessories. It can be used as a border, an all-over pattern, or combined with other stitches to create unique designs.

I wish I had discovered this stitch before starting a queen-sized Temperature blanket. It’s about ¾ done, and I’ll share that project as soon as I complete it, but don’t be surprised to see a border of half-double-crochet spike stitches on it.

Supplies

When I made the swatches shown on this page, I used different colors of yarn so that you could see the spikes easily. 

If you want to use more than one color, I recommend that you change colors every two rows, otherwise you will be weaving in a lot of yarn ends.

Half double crochet spike stitch worked on numerous colors of yarnIf you don't enjoy weaving in ends, I would suggest that you change colors every two rows and carry the ends alongside the fabric.
  • Yarn ( I used a 100% acrylic #4 worsted weight yarn)
  • Hook to match your yarn.(I used an H/5.0 mm hook)
  • Scissors
  • Tapestry Needle for weaving in ends

Notes

  • This tutorial uses US Terms.
  • The fabric is reversible, meaning it looks the same on both sides.
  • Feel free to experiment by working into the row below, two rows below, or more to see how the spikes differ.
  • When pulling up a loop after inserting your hook one or more rows below your current row, ensure that the loop is as tall as your other loops on the hook.  If it is not tall enough, the fabric will pucker, and you won’t be able to get it to lay flat, even with blocking.

Step-by-Step Instructions

For this tutorial, I will explain how to make the spike stitch but not tell you where to place them.  That is entirely up to you and the beauty of this stitch pattern. I will give you some hints, though, if you are struggling with this stitch.

1. Start with a foundation chain of the desired length. For this practice swatch chain 20.

2. Row 1: Hdc in the 3rd chain from the hook and each chain across. Turn. (18 Hdc)

Add an additional row of half double crochet stitches if desired, or go straight to the next step to make some spike stitches.

3. Row 2: Chain 2 (counts as first Hdc), *YO, insert hook into the St 2 rows below (in the foundation chain), YO, pull up a loop, YO, pull through all 3 loops on hook (HDC spike made); repeat from * across. HDC in the last ST. Turn.

Tip:  If you prefer to space out your spike stitches, work one normal hdc, then one spike stitch and alternate across the row.

4. Row 3: Chain 2 (counts as first Hdc), Hdc in each St across. Turn.

5. Row 4: Chain 2 (counts as first Hdc), *Sk next St, YO, insert hook into the St 2 rows below (in Row 2), YO, pull up a loop, YO, pull through all 3 loops on hook (HDC spike made); repeat from * across. HDC in the last ST. Turn.

6. Repeat Rows 3 and 4 until the desired length is achieved.

7. Fasten off and weave in ends.

Additional Tips

  • When working the HDC spike stitch, make sure to insert your hook into the correct stitch in the row below. Counting stitches and using stitch markers can help you keep track of your placement.
  • To create a more pronounced texture, try working spike stitches into rows further below the current row. This will result in longer, more dramatic spikes.
  • The HDC spike stitch can be worked in different multiples to create various patterns. Experiment with skipping different numbers of stitches between spikes to create your desired look.
  • Combining the HDC spike stitch with other stitches, such as the single crochet or double crochet, can add even more depth and interest to your projects.

With practice and creativity, the HDC spike stitch can become a go-to technique in your crochet repertoire, allowing you to create stunning and unique projects that showcase your skills and style.

Conclusion

The HDC spike stitch is a fun and creative way to add texture and interest to your crochet projects. By working stitches into rows below the current row, you can create stunning patterns and designs that are sure to impress.

As you practice this stitch, keep in mind that tension is key. Ensure that your stitches are consistent and not too tight, as this can cause your work to pucker or curl. If you find that your stitches are too loose, try using a smaller hook size.

Experiment with different stitch placements and combinations to create your own unique designs. The HDC spike stitch is a versatile technique that can be used in countless ways to add a special touch to your crochet projects.
