Thorn stitch

Thorn stitch is basically a fancy version of the classic "couching" technique in embroidery, and can be used to stitch a straight line or a curve. You can use thorn stitch to stitch decorative borders, vines, other plants; this would be a great stitch for wreaths, too!

Thorn stitch can be straight, or even curved!

In this post, I'll show you how to stitch thorn stitch in a straight line, as well as in a curved shape - the techniques are slightly different, but involve the same basic steps. If a video is more helpful to your learning process, feel free to scroll all the way to the bottom of this page, where I've provided you with a quick, beginner-friendly video tutorial for both straight and curved thorn stitch.

Straight thorn stitch

Step 1: Draw your guidelines.

I drew three parallel lines for each line of stitching using a white, water-erasable transfer pen. For both straight and curved thorn stitch, you'll use these three lines to help guide you in placing the "base" of your stitch, as well as in placing the "leaves" that couch your base floss to your fabric.

Step 2: Following your middle line as a guide, make one long straight stitch.

Step 3: Bring your needle up through your fabric and create a diagonal straight stitch over your initial straight stitch.

By placing this stitch over your initial straight stitch, you'll be "couching" your base to your fabric.

Step 4: Repeat the previous step, overlapping both your initial straight stitch, as well as the short diagonal straight stitch you made in the previous step.

Step 5: Continue creating short, diagonal, overlapping straight stitches all the way down your line of stitching.

Here's what a finished line of straight thorn stitch will look like, from the front and back:

Curved thorn stitch

Step 1: Draw your guidelines and prepare your floss.

For curved thorn stitch, you'll need two lengths of floss (unlike straight thorn stitch, where you can use just one length of floss). To help demonstrate this stitch, I chose to use two different colors of floss so you can more easily follow what I'm doing. I'll be using the yellow floss to stitch my base, and the green floss to stitch the leaves.

Step 2: Bring your base floss through the top of your center guideline.

For curved thorn stitch, you won't be securing this base to your fabric until you're done "couching" it down with the leaves.

Step 3: Bring your needle up through your fabric and create a diagonal straight stitch over the floss for your base.

This is very similar to straight thorn stitch; the difference here is that you didn't secure your base stitch just yet.
