Knit the Trinity Knit Stitch

I love trying new knit stitches that I’ve never used before. A new stitch can bring texture to your knitting without a lot of effort. The trinity stitch is one of those stitches.

If you’ve ever crocheted, you’ll find this stitch is similar to the popcorn stitch in crocheting. Keep in mind the meaning of trinity — a group of three — and you’ll understand the stitch more easily as you knit in groups of three (k1, p1, k1 into one stitch and purl three together in the next one).

trinity knit stitch - Swatch on Needle

Here’s the pattern we’ll follow:

Cast on a multiple of 4 sts plus 2 sts for edging.
Row 1: K1, *(k1,p1,k1) into next st, p3tog. Rep from * across the row. K last st.
Rows 2 and 4: Purl.
Row 3: K1 *p3tog, (k1,p1,k1) into next st. Rep from * across the row. K last st.

Ready to try it? First, cast on a multiple of 4 sts plus 2 sts so you’ll have a nice edging. I cast on 22 sts for my swatch — that’s five multiples of 4, plus 2 stitches for the edges.

Beginning the Trinity Stitch

Row 1: Knit the first stitch. (Easy enough!) Knit into the next stitch, but don’t drop it from the left needle yet.

Purling with Two Needles

Now you’re going to purl into that same stitch. In order to do that, you need to bring your yarn to the front.

Then purl as you normally would. Don’t drop the stitch from the left needle just yet!

Bringing Yarn to Back

Bring your yarn to the back in preparation for another knit stitch.

Dropping the Stitch from the Left Needle

Drop the stitch from the left needle — finally!

Purl 3 Stitches Together

Purl 3 together (P3tog). This sometimes takes a bit of work and patience to get the right needle to squeeze in there.

This is what your yarn will look like after you complete the first (k1, p1, k1) and p3tog:

Repeating the Pattern for the Trinity Stitch

Repeat the pattern across the row. When you get to the last stitch, k1 for your edging. Notice we’re knitting one at the beginning and the end of the row to keep that edging going.

Don’t freak out if you see that your work has some holes in it. Trinity stitch, you’ll notice from the swatch, does have some openings. Here’s what your work will look like at the end of Row 1:

Row 2: Take a break from the insanity and purl across the row.

End of Row 2 - Trinity Stitch

Row 3: This row is similar to Row 1, except you work in reverse. Knit 1 for the edging.

P3tog as you did in Row 1.

Time for that crazy (k1, p1, k1). Use the same technique you did in Row 1, bringing the yarn to the front to purl and taking it to the back to knit.

Repeat the p3tog and (k1, p1, k1) across the row. Knit the last stitch.

Repeat the 4 rows of the trinity knit stitch until you reach the desired length.

I am going to try this and was looking for a new pattern for scarves and
also going to do an afghan. Thank you!


I’m trying this stitch right now on 10.5 needles with worsted weight yarn. It gives a beautiful textured lacey effect! Your instructions are great: easy to understand and amusing to read. Thank you!


I love this stitch! I just made 2 dish cloths and now starting a baby blanket using very chunky yarn and size 17 needles! So far it is looking sooo great!


I used the Trinity knit stitch to make a beautiful shawl.the pattern is so easy I could take my project everywhere and work on it In my spare time.


I also have used this before, though it was slightly easier. I made a DROPS shawl that called this a blackberry stitch. Instead of K1,P1, K1 in the same stitch, it was K1, yo, K1. I’ve used both but found the yo easier and faster, I didn’t think the appearance was much changed by the different execution of the stitch.

Sounds fun will have to try trinity stitch on next project

Read about this stitch Zen and the Art of Knitting. I couldn’t figure the directions out. Your instructions were perfect. Thank you.


I saw this stitch on a sample in a store, didn’t know what it was called. Now I can make a scarf with 2 colors.


Could you use this stitch in a sweater pattern that is normally done up in regular stockinette stitch?
