Knit Diagonal Stripes Pillow Pattern – Unbiased

This seemingly simple, striped pillow has a secret – it’s knit on the bias! Knit diagonal stripes, then seam them together to make them straight again. The only indication of the unique construction is the diagonal seams and offset stripes at the back.

Lion Brand Vanna’s Choice yarn

Lion Brand originally sent me this Vanna’s Choice yarn for another project. I actually have quite the stash of leftover bits of Vanna’s Choice! With a soft feel and wide range of colors, it’s one of my go-to yarns when I want a good, everyday acrylic. My favorites are the earthy, neutral colors, like the ones I used in this pillow.

Why Unbiased?

This design came about as an experiment in bias knitting. Bias knitting, or knitting on the bias, simply means knitting diagonally. For a square like this pillow, that means working from corner to corner to knit diagonal stripes. But what happens when you take that bias knit fabric and seam it on the bias (along the diagonal edges)?

Folding the corners in makes those diagonal stripes line up straight again. In other words, they become “un-biased”! From the front, it looks like this pillow is just knit straight up in stripes. At the back though, the folded in corners create diagonal seams and an interesting reversal of the striping pattern.

Seaming Tutorial

The visible seams are an important part of this design. So I added a photo and video tutorial just for those! See the seaming tutorial for some great tips on getting a neat and pretty seam.

Bind off: Slip first st knitwise, k2tog, pass slipped stitch over. Cut yarn leaving a 24 inch tail for seaming, and fasten off.

Block your fabric before seaming. It should measure approximately 18 inches square.


The seams are part of the design and should be visible but neat. Take your time with the seaming to make sure everything lines up. Seaming tutorial coming soon!

Lay square flat with wrong side up. Fold 2 corners in so that they meet in the center with RS up.

Line up striped sections and seam adjoining edges using the following rules:

  • Always seam into the stitch that is one stitch in from the edge. This will be just behind the garter stitch selvedge.
  • Each garter ridge has 2 lines of bumps – top and bottom. When working into garter stitch, on one side of the seam work into the top bump of the ridge, and on the other side work into the bottom bump of the ridge. In both cases, insert needle from top to bottom.

  • When working into stockinette, work into one loop of the increase or decrease stitch at the edge. Choose the loop furthest from the edge, and insert needle so that it points towards the seam.
  • Where stockinette meets garter in the striped section, one garter ridge should line up with 1 row of stockinette. The garter ridge is 2 rows, but it is more compact, so it works out evenly this way.
  • After each section, pull the seaming thread snug. The seam should come together firmly, but not pucker.

Repeat for remaining corners, leaving only one seam unworked.

Sew in all tails except for the one you plan to use for the last seam.

Insert pillow form, then seam remaining edge and weave in end. .

Optional Button(s)

If desired, either sew a button over the center of the pillow only on the side where the seams meet, OR place one button in the center of each side of the pillow and sew them together, going through the center of the pillow.
