REVERSIBLE DUO KNIT VEST – PATTERN AND TUTORIAL

In today’s free tutorial, I’ll show you how to knit the flat version of the DUO Knitted Vest using two needles. If you prefer knitting in the round, the circular version is available in the PDF patterns. Choosing the circular method allows you to skip sewing the sides at the end.

The DUO Knitted Vest is worked as a single piece and then joined at the sides to create its final shape.

We’ll begin by knitting the lower front section, then separate the stitches to shape one armhole, the neckline, and the shoulder. Next, we’ll repeat the process to form the other side of the neckline. Once the front is complete, we’ll join the two shoulders at the back of the neck and knit the back panel. Finally, we’ll pick up the reserved neck stitches to knit the back neckband and finish the vest.

How to Knit the DUO Reversible Vest (Size S) on Two Needles

Important Note

For this pattern, all stitches on even rows should be knitted as they appear:

  • If a stitch appears as knit, knit it.
  • If a stitch appears as purl, purl it.
    Exceptions will be clearly stated in the instructions.

Front Section:

Knit the Bottom and Front Body

  • Cast on 95 stitches.
  • Work 16 rows in 1×1 Rib as follows:
    • Odd rows: Alternate 1 K st, 1 P st to the end.
    • Even rows: Knit the stitches as they appear: 1 P st, 1 K st to the end.

Once the bottom of the knitted vest is completed, on row 17 and odd rows up to row 87, you must knit 8 sl st (Rib Stitch), 31 sts.k, 17 sl st, 31 sts.k, 8 sl st.

Knit even rows as they come.

Forming the Armhole and Right Neckline

At this stage, we’ll begin shaping the armholes and V-neckline.

On the next purl row, knit 8 selvedge stitches, purl 31 stitches, and knit 8 selvedge stitches. Place the 47 stitches just worked on a stitch holder. Then, continue by knitting 2 stitches together, knitting 7 selvedge stitches, purling 31 stitches, and knitting 8 selvedge stitches.

From here on, you will only work the stitches that form the right shoulder of the vest.

To shape both the armhole and neckline, decrease 1 stitch on the odd rows for the armhole area, and 1 stitch every two odd rows for the neckline.

Start the decreases 8 stitches in from the edge of the work. After knitting the 8 rib stitches, do a simple decrease (surjete). When you have 10 stitches left in the row, knit 2 together and finish with the last 8 stitches in rib.

Example Decrease Rows:

  • Row 89: 8 PE, dec, 27 K, K2tog, 8 PE
  • Row 91: 8 PE, dec, 27 K, 8 PE
  • Row 93: 8 PE, dec, 24 K, K2tog, 8 PE

Continue decreasing in this pattern until you have 35 stitches remaining on your needle.

Once we have obtained these 35 stitches, we have finished decreasing to form the armhole of the Knitted Vest with two needles, but we will continue decreasing every two odd rows to shape the neckline area until we obtain 26 stitches.

Knit the Right Front Shoulder

To complete the right shoulder, knit 11 more rows without any decreases. Be sure to knit the first 8 and last 8 stitches in Rib Stitch (PE) on each row.

Once finished, place the 26 stitches on a stitch holder for later use.

Form the armhole, neckline and left shoulder

Once the first armhole, neckline and shoulder have been formed, we will resume the stitches reserved for the other part by returning them to our working needle.

You should knit in the same way; decreasing 1 stitch on the odd rows in the armhole area and 1 stitch every 2 odd rows in the neckline area until you have 355 stitches, continue decreasing only every 2 odd rows in the neckline area until you have 26 stitches and finish by knitting 11 more rows to give it height.

Knit the Back of the Reversible Knit Vest

Join the Two Shoulders at the Back of the Neck

Once the front is complete, it’s time to join the two shoulders at the back of the neck to continue with the back of the vest.

  • In a purl (even) row, knit 8 selvedge stitches (sl sts), purl 10 stitches, and place the next 8 ribbed stitches on a stitch holder.
  • Cast on 43 stitches.
  • Transfer the 8 stitches from the opposite shoulder (previously set aside) to the working needle, excluding the 8 selvedge stitches closest to the neckline, which will remain on the holder.
  • Knit 10 stitches, then purl the 8 selvedge stitches to complete the row.

After knitting this row you will end up with 79 stitches on your working needle and two stitch holder needles on either side of the neckline with 8 stitches on each.

Knit the upper back area
To form the upper back area, knit these 79 sts for 44 rows. You will continue to form the pattern by knitting 8 sl st, K 23 sts, 17 sl st, K 23 sts, 8 sl sts on the odd rows and on the even rows all the sts as they present themselves.

Form the armholes

To form the armholes, begin increasing 1 stitch on each side, 8 stitches from the edges, until you have a total of 95 stitches. For the first row of increases, start by knitting 8 selvedge stitches (sl sts), then increase 1 stitch to the left (M1L). Knit 23 stitches, followed by 17 selvedge stitches (sl sts), and then knit another 23 stitches. Finally, increase 1 stitch to the right (M1R) and knit the last 8 selvedge stitches. Continue increasing in this way on each row until you reach the desired stitch count.

Once you have finished your increasing rows, knit these 95 stitches for 72 more rows, maintaining the pattern, and finish with 16 more rows of Rib. Cast off all the stitches.

Knit the back of the neck area

To knit the back of the neck area, return the 8 reserved stitches to your working needle and knit 43 rows in Rib Stitch. Once finished, without casting off, join these 8 stitches to the other 8 stitches on the stitch holder using a vertical blind seam or Kitchener Stitch. If you prefer, you can close the stitches and sew them in a way that feels most comfortable, aiming to make the seam as discreet as possible.

Once the two parts are joined, sew the neck to the base.

Final finishes

Fold the garment over the shoulders and sew the sides using an invisible side seam, stopping at the Elastic Stitch area to leave a small opening. It’s crucial to ensure the seam is as invisible and uniform as possible on both the inside and outside, so your knitted vest remains reversible and can be worn on either side.

If done correctly, the seam will be virtually invisible; however, if you choose to knit your DUO Vest in the round, you can skip this step. The round version is available in the PDF pattern.

Once finished, tie up any loose ends. While blocking is not required, soaking the garment in warm water, removing excess water with a towel, and letting it dry on a flat surface will help even out the stitches and achieve the best results.
