Blackberry Stitch, aka Trinity Stitch, in the Round

Trinity blackberry Stitch knitting

Knitting blackberry stitch, AKA Trinity stitch, in the round.

I couldn’t find a straightforward explanation for knitting blackberry stitch — also known as the trinity stitch — in the round, so here goes:

Knit in multiples of four rows until your desired length is reached. 

Row 1: Purl all stitches.

Row 2: *k3tog, (p1, k1, p1) into the next stitch; rep from * to end.

Row 3: Purl all stitches.

Row 4: *(p1, k1, p1) into the next stitch, k3tog; rep from * to end.

Some notes:

  • This stitch sequence is knit in multiples of four stitches across four rows.
  • Your first and third rows are purled. If you tend to be a tight knitter, you might try to loosen up for these rows, otherwise you will have a difficult time trying to work this stitch pattern. Knit too tightly and you will snap the yarn, break the needle, or give yourself carpal tunnel symptoms. Seriously.
  • Your second and fourth rows are the “active” rows. If you thought knitting two stitches together could get tight, just wait until you knit three together. Because the next three stitches are worked on one single stitch to create the “blackberry,” this too can get stressful for the yarn and needles. Keep these stitches intentionally loose.
  • It’s important to remember that when doing your pkp pattern on your blackberry that you don’t slide the anchor stitch off the left needle until all three stitches in it are complete. You’re making three stitches on one, then decreasing in the same row with the k3tog.

I’m currently knitting a hat from the bottom up. CO 92, (k1,p1) for ~30 rows, then blackberry stitch until I decrease. I’ll let you know how it goes.

EDIT: It was cute! The little bobs of yarn give you so much texture.
