PATTERN OVERVIEW ABBREVIATIONS
The piece begins by working increases to form the RS - right side
top of the front piece. A double-knit top edge is WS – wrong side
added, and the process is repeated for the back k – knit stitch
piece. The two pieces are joined, and the body is p – purl stitch
worked to the desired length with optional short sl – slip stitch
rows for bust shaping and decreases for waist wyif – with yarn in front
shaping. Stitches are picked up at the sides of the SM – stitch marker
front and back to work the straps in double knitting. m1l/m1r – make 1 left/make 1 right
The body is completed with a fold-over hem. m1lp/m1rp – make 1 left/make 1 right
k2tog/p2tog – knit/purl 2 together
GAUGE SWATCH ssk – slip 2 sts k-wise, insert resting needle in
Be sure to make a swatch to ensure your gauge front of 2 slipped sts and k2tog tbl
matches that specified in the pattern. If your gauge tbl – through the back loop
does not match, your finished garment may not be BOR – beginning of the round

THE PATTERN BEGINS HERE:

FRONT PIECE
Enter your upper bust measurement: ________ (inches) and your full bust measurement: ________ (inches).
(Measurement should be taken under the arms).

[description]: the front piece is worked top-down for a short length back and forth. Then, stitches are added
on both sides with 3 sets of increases to create shape around the arms. After the increases are completed,
live stitches are placed on a stitch holder/scrap yarn while the neckline edge is worked.

Cast on (A) _______ sts using the long tail cast on.

Purl 1 row.
|| Row 1 (RS) ||: knit all sts
|| Row 2 (WS) ||: purl all sts
Repeat Rows 1-2 until the piece measures 0.5” or 1.25 cm from the cast on edge. The next row is a RS row.

Increases 1
|| Row 1 (RS) ||: k2, m1r knit across until 2 sts, m1l, k2 – (# of sts has now increased by 2)
|| Row 2 (WS) ||: purl all sts
|| Row 3 (RS) ||: knit all sts
|| Row 4 (WS) ||: purl all sts

Work rows 1-4 a total of three times (i.e., twice more) for a total of 6 sts increased or, (B) _______ sts are on
the needles. Then next row is a RS row.

Increases 2
|| Row 1 (RS) ||: k2, m1r, knit across until 2 sts, m1l, k2 – (# of sts has now increased by 2)
|| Row 2 (WS) ||: purl all sts

Repeat rows 1-2 until (C) _______ sts are on the needles. The next row is a RS row.

Increases 3
|| Row 1 (RS) ||: k2, m1r, knit across until 2 sts, m1l, k2 – (# of sts has now increased by 2)
|| Row 2 (WS) ||: p2, m1lp, purl across until 2 sts, m1rp, p2 – (# of sts has now increased by 2)

Repeat rows 1-2 until (D) _______ sts are on the needles. Next row is a RS row.
If you have completed all increases on a RS row, knit one more row without increases so that a WS row is
the last row knit. Set this piece aside on a stitch holder or scrap yarn. Cut the yarn.

9PM TANK © KNTT ● TIFFKNIT OCTOBER 2022 3 of 13

Neckline Edge
[description]: stitches will be picked up along the cast on edge then the yarn is cut. Returning to the start of
the pick-up, new stitches are casted onto the resting needle. Now, double knitting begins on the RS starting
with the newly cast on stitches. The last stitch that was cast on will be knit together through the back loop
with the first stitch that was picked up. The work is turned, and double knitting continues but this time,
starting with slipping the first stitch instead of knitting it.

Pick up every 4 of 5 (i.e., pick up 4 sts, skip the 5th one and repeat across). This will be approximately (E)
_______ sts picked up. Cut the yarn to a length long enough so that it can be woven in later (i.e., at least 3
inches or 7.75 cm).

Return to the start of the pick-up. On your resting needle, cast on 9 sts using a long tail cast on or
whichever method is preferred. Now, double knitting begins:

|| Row 1 (RS) ||: k1, sl1wyif, repeat until 2 sts remain, kt2og tbl. Turn the work. [10 sts worked total]
|| Row 2 (WS) ||: sl1wyif, k1 until there is 1 stitch left, sl1wyif. Turn the work. [9 sts worked total]

Repeat rows 1-2 until all the stitches that were picked-up are worked.
Bind off all k sts in k and all p sts in p.

BACK PIECE
[description]: The back piece will start off wider than the front piece as it will sit lower/be shorter than the
front piece. It will be worked in the same way as the front piece starting at ‘Increases 2’.

Cast on (B) _______ sts with a long tail cast on.

Work 3 rows in stockinette starting on the WS (Purl 1 row, knit 1 row, purl 1 row).

Increases 2
|| Row 1 (RS) ||: k2, m1r, knit across until 2 sts, m1l, k2 – (# of sts has now increased by 2)
|| Row 2 (WS) ||: purl all sts

Repeat rows 1-2 until (C) _______ sts are on the needles.
The next row is a RS row.

9PM TANK © KNTT ● TIFFKNIT OCTOBER 2022 4 of 13

BACK PIECE Continued

Increases 3
|| Row 1 (RS) ||: k2, m1r, knit across until 2 sts, m1l, k2 – (# of sts has now increased by 2)
|| Row 2 (WS) ||: p2, m1lp, purl across until 2 sts, m1lr, p2 – (# of sts has now increased by 2)

Repeat rows 1-2 until (D) _______ sts are on the needles.
Next row is a RS row. If you have completed all increases on a RS row, knit one more row without increases
so that a WS row is the last row knit.
Set this piece aside on a stitch holder or scrap yarn.

Neckline Edge
[description]: worked the same way the neckline edge from the front piece was worked.

Pick up every 4 of 5 (i.e., pick up 4 sts, skip the 5th one and repeat across). This will be approximately (F)
_______ sts picked up. Cut the yarn to a length long enough so that it can be woven in later (i.e. at least 3
inches or 7.75 cm).

Return to the start of the pick-up. On your resting needle, cast on 9 sts using a long tail cast on or
whichever method is preferred. Now, double knitting begins:

|| Row 1 (RS) ||: k1, sl1wyif, repeat until 2 sts remain, kt2og tbl. Turn the work.
|| Row 2 (WS) ||: sl1wyif, k1 until there is 1 stitch left, sl1wyif. Turn the work.

Repeat rows 1-2 until all the stitches that were picked-up are worked.
Bind off all k sts in k and all p sts in p.

JOINING IN THE ROUND

[description]: both front and back pieces should be placed on a cord that suits your full bust measurement
with the front piece on the needles behind the back. New stitches will be cast on between the pieces as you
work across to join both pieces in the round.

The calculator provides a stitch counts for two different fit options: (G1) and (G2) sts. If more negative ease
at the bust is preferred, cast on (G1) sts, if more neutral ease if preferred at the bust, cast on (G2) sts. Your
choice to use (G1) vs (G2) will correspond with either (H1) or (H2) (i.e. (G1) à (H1) and (G2) à (H2)).

Work across the back piece sts, cast on (G1)/(G2) _______ sts and place a SM in the middle, work across
the front piece sts, cast on (G1)/(G2) _______ sts and place another SM in the middle, place a BOR marker.

There are now (H1)/(H2) _______ sts total in the round (2 SMs with half the sts between each and one BOR).

Knit in the round for 1 inch or 2.5 cm (or 11 rounds).

After joining in the round, it is recommended to move to the ‘STRAPS’ section. Having the straps
completed makes the knit wearable and will just require adding length and decreases (if applicable).
Having the knit wearable allows you to better determine where the short rows will sit and how long you
would like your garment to be.

9PM TANK © KNTT ● TIFFKNIT OCTOBER 2022 5 of 13

SHORT ROWS (OPTIONAL)
[description]: short rows will form a bust dart to improve fit for a larger chest. Enter your over bust and side
bust measurements into the calculator (instructions on how to take this measurement below). The calculator
provides a ‘yes’ or ‘no’ based on the over bust – side bust difference. If ‘No’, skip to ‘DECREASES’ section.
See Adjustments before beginning short rows.

Short rows? ____Yes ____ No (skip to ‘DECREASES’ if No; skip to ‘THE BODY’ if no short rows or decreases)

Adjustments: where the short rows are placed will depend on the point of your bust. How high or
low our bust sits will vary from person to person. If your bust sits higher/if you are petite, knitting in
the round for 1 inch or 2.5 cm should be sufficient. If your bust sits lower, knit 2 inches or 5 cm in
the round before beginning the short rows. For a more accurate placement of the bust dart, see
the following measurements:

Measure from the tip of your shoulder straight down to the peak/fullest part of your bust. Subtract
10 inches or 25 cm from your measurement. This number ( ______ ) is the additional length after
the 1 inch or 2.5 cm that should be knit in the round, before beginning your short rows.

For reference: those with a smaller bust size typically had a difference around 0.7-1” while those with a
larger bust had differences around 2-3.5”

Knit to the start of the round.

RS: Continue to knit until there are (I) _______ sts before the side SM. Knit 2, wrap the next stitch, and turn.
WS: purl across until there are (I) _______ sts before the other side SM. Purl 2, wrap the next stitch, and
turn.

9PM TANK © KNTT ● TIFFKNIT OCTOBER 2022 6 of 13

SHORT ROWS Continued

Detailed Instructions on ‘Wrap and Turn’:

“Wrap and Turn”: slip the next stitch k-wise onto your working needle, bring the yarn to the other side, slip
the same stitch back on to your resting needle, bring the yarn back, turn the work. When you return to the
wrapped stitch on the next row, work both the wrapped part and stitch together.

RS: knit across until the wrapped

stitch. Knit this stitch and one more.
Wrap the next stitch and turn.

WS: purl across until the wrapped

stitch. Purl this stitch and one more.
Wrap the next stitch and turn.

Continue until 4 stitches before the side SMs have been worked on both the knit and purl side. The next
row is RS row. Knit all sts in the round.

DECREASES (OPTIONAL)
[description]: if desired, decreases are used to create shaping towards the waist. Four stitches will be
decreased for each decrease row at an interval defined by your waist measurement.

|| Step 1 ||: Knit until 3 sts before the first side SM, ssk, k1, slip SM, k1, k2tog. Knit until 3 sts before next
side SM, ssk, k1, slip SM, k1, k2tog – (# of sts has decreased by 4)
|| Step 2 ||: Knit (J) _______ round(s) without any decreases.

Repeat Steps 1 and 2 (K1)/(K2) _______ sts times or until there are (L) _______ sts left (length should be
around the smallest part of waist). Remove the BOR marker after a few repetitions of decreases are made
and treat the closest SM as new BOR.

Your choice to use (K1) vs (K2) will correspond with whether your used (G1) or (G2) in the Joining in the
Round section (i.e. (G1) à (K1) and (G2) à (K2)).

Continue to work in the round with no decreases until your desired length. You may knit to 7 inches or 18
cm for a cropped length and 10.5 inches or 27 cm for a full length, measured from the join at the
underarm to the purl row.

9PM TANK © KNTT ● TIFFKNIT OCTOBER 2022 7 of 13

THE BODY
[description]: continue to work in the
round until the desired length. A fold-
over edge is then worked before binding
off. Note: the fold-over edge will not add
any additional length but will create a
visible 1.5” or 4 cm hem line.

Once desired length has been reached,

purl 1 round. Knit 16 rows. Fold the
edge towards the WS of the work and
knit the next round with the 16th WS
round above the purl row and bind off
using stretchy bind off method.

STRAPS
[description]: stitches are picked up
along the side of the front piece, the cast
on sts under the arm, and along the side
of the back piece (for the other strap you
pick up will begin with the side of the
back piece first), then the yarn is cut.
Stitches are slipped on to your working
needle until the centre of the underarm
is reached.

Using an extra long cord (48”) will make

things easier here. Pick up every 3 of 4
sts (i.e., pick up 3 and skip the 4th,
repeat) from the double-knit edge of
back piece to the front piece. Cut the
yarn to a length long enough so that it
can be woven in later (i.e., at least 3
inches or 7.75 cm).

Slip sts to your working needle until the

middle the underarm (the point marked
with a star). Pull your working needle out
so that these slipped sts rest on the
cord. This will give you more flexibility to
work the next step.

On your resting needle, cast on 11* sts using a long tail cast on or whichever method is preferred.

*To Customize Strap Thickness: decrease or increase number of sts cast on by intervals of 2 sts to make a
thinner or thicker strap. Casting on 11 sts creates a strap that is about 0.75 inches or 2 cm thick.

Now, double knitting begins:

|| Row 1 (RS) ||: k1, sl1wyif, repeat until 2* sts remain, kt2og tbl. Turn the work.
|| Row 2 (WS) ||: sl1wyif, k1 until there is 1 stitch left, sl1wyif. Turn the work.

*The 2 sts that remain = 1 that was cast on and 1 that was picked up.

9PM TANK © KNTT ● TIFFKNIT OCTOBER 2022 8 of 13

STRAPS Continued

Repeat rows 1-2. Work across all picked up sts then, continue to work unattached for about 12 inches or
30.5 cm. One way to guide your measurement is to measure the strap length of a bra or tank and subtract
2 inches or 5 cm to account for the stretch.

Slide the resting needle forward so that the strap sts are on the cord; slide them next to the picked up sts.
Pull the working needle forwards so that the live sts are now on the resting needle. Continue to work the
double-knit strap while attached (i.e., Row 1 and 2 above). Repeat until all picked up stitches are worked.

Note: at this point, double check to ensure the strap is in the right orientation and not twisted before
joining with the picked up sts from the other piece.

Bind off all k sts in k and all p sts in p. Seam with beginning.

Block the garment and seam in the ends.

Note: pull the ends that connect the straps to the body of the piece tightly so that there is no gap between
these pieces.

The end.
