Today’s the day, the first square of our 2019 Stash Busting Sampler Afghan is here! The first square features the herringbone half double crochet stitch (Hbhdc).

This crochet stitch is a fun little twist on the traditional half double crochet , the stitches end up with a slant and when you work it back and forth in rows it creates an arrow shape. The fabric it creates it pretty smooth but the “arrows” give it lots of interest.

How to Herringbone Half Double Crochet

When you crochet a herringbone half double crochet there is only step that is different from a traditional half double crochet. To make a hbhdc, yarnover and insert your hook into the stitch. Yarnover again and instead of pulling it through just the stitch, your’e going to pull it through the stitch AND the first loop on your hook. Then you’ll complete it by doing another yarnover and pulling through both of the loops on your hook. Its pretty easy and quick once you get the hang of it.

I was going to make a photo step by step of the the stitch but I thought I would throw together a quick little video instead! I try and do a quick video tutorial for each of our squares. They will all be posted on my Facebook Page and I will also share them into my Facebook Group.

You do You!

For this square I used 2 different colors. I was going to just do a solid color but then I thought it would be fun to make it color-blocked. Feel free to experiment with your square!! Stripes, solid, 2 colors, 3 colors; it’s all up to you. I can’t wait to see them. Hop on over to the group on Facebook and share them!

I also thought it would be fun to make a little hashtag to use on Instagram if that’s your jam. I came up with #2019StashBustingCAL. I thought this would be a fun way for us to see all the squares together… and who knows yours might even make an appearance in my Insta-stories!

    Good morning, I watched your video, my first time watching one of yours. It was fabulous! Honestly! I’ve been crocheting for 36 years so rarely watch any, but for some reason felt compelled to watch yours. You have excellent teaching skills! Very clean and clear, never blocking with your hands, and showing the stitch slowly multiple times. I’m impressed!

  2. M'Lisse Haas says:

    So excited for this! The video is perfect and especially helpful as I am new and learning stitches. My 2019 challenge. Thanks!

  3. Shawna says:

    Question, maybe a silly one but I see the gauge says 7st by 6 rows but I don’t see how big it should measure if that makes sense?

  4. SusanB says:

    Sadly, I was not able to watch your video. I do not do Facebook — don’t trust it with my information. Perhaps after posting on Facebook, you could put a copy on YouTube like Bonnie Hunter does with her QuiltCam videos.

  5. CrochetCarie says:

    Nice CAL. I’ve already completed the first square. Question though, how do you plan on joining the squares? There doesn’t seems to be a set amount of stitches on the sides of the square for joining.

  6. Susan Looney says:

    Hello! I am doing your CAL in DK. I’m using a 5mm hook and measuring as I go to get the correct size. Have you any other advise for me doing this in DK? I’d really appreciate it,
    Sue x

  7. Gloria james says:

    Ok what am I doing wrong when I chain one and go into same stitch with the herringbone double crochet it seems to be backwards not on same side as the first row am I doing it wrong?

    • Heather says:

      Do you mean the stitch looks backwards? I think your doing it right. When you turn and go to the next row the stitch will look like it leans opposite of the row below.
