Star Trek Colourwork Motif Christmas Jumper — Top‑Down Yoked Raglan

Bright, wearable festive jumper with a Star Trek inspired delta chevron colourwork motif across the yoke. Constructed top‑down with raglan increases so you can try on as you knit. Colourwork is stranded (Fair Isle) — motif chart included. Please note this is a fan pattern inspired by Star Trek aesthetics and intended for personal/craft use.

XS: 32" / 81 cm
S: 36" / 91 cm
M: 40" / 102 cm
L: 44" / 112 cm
XL: 48" / 122 cm

Yarn (DK / Light Worsted / 8 ply)

Gauge and yardages below assume a DK weight yarn. Typical DK: ~225 yds (205 m) per 100 g skein.

Main color (MC, background): 900 (1000, 1100, 1250, 1400, 1550, 1700) yards / 820 (915, 1006, 1143, 1280, 1417, 1555) metres. (Approx skeins: 4 (5,5,6,7,8,8) x 100g)
Contrast A (gold/starfleet delta): 100 (150,150,200,200,250,250) yards / 90 (137,137,183,183,229,229) metres.
Contrast B (red/chevron accent): 100 (100,150,150,150,200,200) yards / 90 (90,137,137,137,183,183) metres.
Contrast C (black / outline): 50 (50,50,50,50,50,50) yards / 45 (45,45,45,45,45,45) metres.

Choose high‑contrast colours for the motif: a warm gold or yellow, bright red, and black or very dark navy for outlines on a white/cream or deep green MC for a Christmas look.

Needles

Use circulars for body and yoke; DPNs or small circular for neck/cuffs if you prefer.

Ribbing: US 4 / UK old 9 / 3.5 mm (one size smaller if you need firmer rib)
Body & colourwork: US 6 / UK old 8 / 4.0 mm
Optional smaller/larger to obtain gauge: try US 5 / 3.75 mm or US 7 / 4.5 mm
Circular lengths suggested: 16" / 40 cm (for neck), 24–32" / 60–80 cm (for body and yoke)

Gauge

22 sts x 30 rnds = 4" / 10 cm in stockinette in the round on 4.0 mm (US 6). IMPORTANT: Check your gauge with stranded fabric — floats and tension affect gauge.

Abbreviations

CO = cast on
K = knit
P = purl
K2tog = knit two together
M1 = make one (lifted increase as described)
RS = right side
st(s) = stitch(es)
MC = main colour
CA/CB/CC = contrast colours
YO = yarn over

Notes & technique

This is a stranded colourwork yoke. Carry floats loosely across back — catch long floats every 3–4 sts if floats exceed 5 sts.
Work raglan increases every other round (4 increase points) and place stitch markers after CO to mark raglan lines.
When separating sleeves, put sleeve sts on waste yarn or holder and continue in the round for the body.
Blocking after finishing evens stranded fabric and opens the yoke motif.

Construction Overview

1) CO for neck and work yoke ribbing. 2) Establish raglan markers and increase rounds while working motif across the front/yoke using the chart. 3) When yoke length achieved, place sleeve sts on holders and continue body in MC. 4) Pick up sleeve sts, knit in the round, work colorwork detail at upper sleeve if desired, then cuff ribbing.

Cast On & Yoke Setup

Using 3.5 mm (US 4), CO neck sts as follows (adjust counts to fit gauge and size):

XS: CO 132 sts
S: CO 140 sts
M: CO 152 sts
L: CO 164 sts
XL: CO 176 sts
2XL: CO 188 sts
3XL: CO 200 sts

Join carefully to work in the round, place 4 raglan markers dividing the round into front, sleeve, back, sleeve sections. Work 2" / 5 cm of 1x1 rib (K1,P1) on 3.5 mm. Switch to 4.0 mm and begin pattern round.

Raglan increase

Every RS round: K to 1 st before marker, M1, K1, slip marker, K1, M1. This gives 8 sts increased every two rounds (4 increase points x 2 rounds), or you can do increases every other round as you prefer; keep increases evenly spaced. Continue increases until you reach the yoke depth measured from neck: XS 8.5" / 22 cm; S 9" / 23 cm; M 9.5" / 24 cm; L 10" / 25.5 cm; XL 10.5" / 27 cm; 2XL 11" / 28 cm; 3XL 11.5" / 29 cm — or until the underarm circumference (total sts between raglan markers for body) measures approximately the desired chest divided by your stitch gauge.

Separating sleeves

When raglan increases complete, place sleeve sts on holders: slip sleeve stitch groups onto waste yarn; join MC and continue in the round for the body. Continue in stockinette until body length from underarm equals: 16" / 41 cm (XS), 17" / 43 cm (S), 18" / 46 cm (M), 19" / 48 cm (L), 20" / 51 cm (XL), 21" / 53 cm (2XL), 22" / 56 cm (3XL). Work 2" / 5 cm 1x1 rib with 3.5 mm, bind off loosely.

Sleeves

Transfer sleeve sts to 4.0 mm circular or DPNs, pick up 2 sts underarm if needed to avoid gaps. Decrease sleeve to fit (optional). Typical sleeve length to wrist: 17" / 43 cm (XS) up to 20" / 51 cm (3XL). Work 2" / 5 cm rib on 3.5 mm and bind off.

Colourwork yoke motif

The motif is worked across the front panel of the yoke and mirrored on the back with repeats around the yoke. Chart given below is a 24‑st wide delta chevron motif; place it centred on the front and repeat or mirror across the back as needed for your stitch count. Use stranded knitting: carry unused colour behind work, keeping floats loose but tidy.

Key

MC = m background (use white/cream or green)
GA = gold (delta fill)
RB = red (accent)
BL = black (outline)

Chart (24 sts wide x 16 rows high). Read right to left on odd-numbered rows (RS) and left to right on even-numbered rows when working flat; since jumper is in the round read every row right to left. Copy chart and centre in front. Characters: m=MC, g=GA, r=RB, b=BL.

Notes on chart: Row1 is the row closest to the neck; work rows in sequence as you increase the yoke. The chart uses a centered delta motif with outline stitches inserted to make the delta read sharply in stranded knitting. If you prefer to position motif across the entire yoke, repeat motif panels across the round; plan repeats so raglan increase lines fall in single‑colour MC sections where possible.

Stranded tension & float management

Keep two active colours in each small area where possible to avoid long floats.
When carrying colours across more than 4–6 sts, catch the float by twisting the yarn around the working yarn once to prevent a loose float.
Work stranded floats on the inside of garment; do not pull contrast yarns too tight — maintain even tension.

Finishing

Weave in ends on inside; for stranded work, weave ends under floats for neatness.
Block gently to measurements — steam or wet block based on yarn fibre content. Blocking will even motifs.
Add festive details (sewn sequins, subtle metallic embroidery) sparingly if desired — avoid covering the motif so trademarked shapes remain recognisable.

Sizing adjustments

To change finished circumference, adjust number of plain MC rounds before separating sleeves, or increase/decrease CO in multiples of the motif repeat (24 sts) so the motif remains centered. For a tighter or looser fit, swap needle sizes and re‑measure gauge.

Troubleshooting

Motif appears stretched: your stranded tension is too tight — relax your floats or go up a needle size for the yoke round(s).
Gaps where sleeve joins body: pick up 1–2 extra sts at underarm and decrease over first 2–4 rounds.
