I’m loving these poncho sweaters! I wanted a simple sweater that’s relatively quick to knit with lots of squishy texture!

I’m so glad that the boxy look is in style, it’s just comfy! So, I made this poncho a little oversized so it’s super cozy.

I hope you enjoy this new pattern.
Happy knitting 🖤!

Techniques

Here are some of the knitting skills you need to know before getting started:

Knit Flat
Knit & Purl Stitches
Sew Seams

For this poncho pattern you simply knit 2 rectangles, from top to bottom and then seam them together. No increase stitches, no decrease stitches, just knit and purl stitches!

Yarn & Substitutions

Yarn Weight: Super Bulky
Yardage: 236 – 668 yards (216 – 611 meters)
Suggested Yarn: Cloudborn Fibers Highland Roving

Alternative Yarn Substitute Options:

Unfortunately, this chunky yarn is no longer available. So, here’s a list of alternative yarns:

I’ve worked with the first 3 options on multiple projects and they’re almost identical to the yarn used for the poncho, so they’re great options!

Rows 2, 4 (RS): *K1, P1* last stitch: K1

Body, Moss Stitch:

Row 6 (RS): *P1, K1* last stitch: P1 (knit the purls and purl the knits)

Row 7 (WS): *K1, P1* last stitch: K1 (knit the knits and purl the purls)

Row 8 (RS): *K1, P1* last stitch: K1 (knit the purls and purl the knits)

Row 9 (WS): *P1, K1* last stitch: P1 (knit the knits and purl the purls)

Repeat rows 6-9 according to the “Size” chart above, or until desired length, minus the bottom ribbing.

Bottom, 1×1 Rib Stitch:

Row 1, 3 (RS): *P1, K1* last stitch: P1

Row 2, 4 (WS): *K1, P1* last stitch: K1

Row 5 (RS): BO in the P1, K1 pattern

Knit the 2nd side the same as the first.

The front and back are the same.

*Sew seams along the red lines.

Top Seams:

Put the wrong sides together.

Starting from the outside, seam the top seam, leaving a hole large enough to fit your head through and maybe show a little shoulder. My head hole width measures 12″/30cm. Make sure the seams from the outside to the inside are the same measurement on each side.

Side Seams:

Starting from the bottom, seam each side using the mattress stitch, leaving a hole just large enough to fit your hand and arm through. My arm hole measures 7″/18cm.

Weave in the ends.

Steam-block lightly, which will add 1-2″/3-5cm of length and soften the stitches for a relaxed drape.
