Treena Jumper – Free Knitting Pattern

As with most things, this sweater has a backstory. However, that story is for another day. For now, this pattern is available for free, and the story will follow later. The size is a medium women’s (Size 12-14 NZ). I may add alternative sizes later. (I wear an XL, and this jumper does fit me as a fitted garment, but it is designed to be more snuggly on a smaller bod. However, I have not convinced my sister to model it). It is an easy knit with a slimming centre detail, and raglan sleeves, which make it a very comfortable knit to wear.

There will be a YouTube video covering the making process of this jumper, and a short tutorial for the feature detail down the front and back of the jersey.

Finished jumper – on an XL sized human. Designed to fit M-L with a relaxed fit… but it works as a fitted jumper on a bigger human.


Cast on 101 stitches on 3.5mm needles
Rib K1xP1 over 20 rows

Change to 4.5mm needles. Place 2 stitch markers – one after 48 stitches, and one after stitch 53. This will contain the centre detail (and be very useful in setting up the pattern, and during the raglan sleeve section)

Right side row: K48, slip marker, p2, k1b, p2, slip marker, k48
Inside side row: P48, slip marker, k2, p1, k2, slip marker, p48

Centre detail

A how-to video of this stitch detail can be found here:

Knit until back measures 41cm. At the start of the next 2 rows, cast off 5 stitches remembering to continue the centre front detail. Keep the centre stitch markers in place and continue the centre detail pattern between these stitches, as you will now be shaping the raglan top.

Every right side row: SSK, knit to marker, slip marker, p2, k1b, p2, slip marker, knit to last 2, k2tog
Every inside side row: Purl to marker, slip marker, k2, p1, k2, slip marker, purl to end

Continue the decrease until 21 stitches remain. Slip these onto scrap yarn (and tie up loosely to pick up later) or a large stitch holder for the top collar.

Complete as for the back until 41 stitches remain.
Ssk, knit 21 stitches, slip the next 5 stitches onto a safety pin for later. (This is the centre detail piece by the way). Turn work and continue working just this section for the moment.

All the finished panels

You now have all the pieces. Lay them out and stitch the arms to the body pieces. Leave 1 raglan edge open. Pick up the stitches around the collar and the stitches that have been reserved on pins. Do this on the 3.5mm knitting needles.

Ready to pick up stitches for the collar

K1xP1 rib for 5 cm. Cast off loosely (or your neck will be too tight). Pin the sleeves and sides together. Stitch up the final raglan edge. Stitch up the sleeves and sides. Darn in your yarn tails.
