## SPECIAL TECHNIQUES
**Intarsia:** Use separate balls of yarn for each colour section. Twist yarns when changing colours to prevent holes.

## BACK
Using 4.0mm needles and MC, cast on 84 sts.
Work in 1×1 rib for 6cm.

Change to 4.5mm needles.
Next row (inc row): K6, *inc 1, k10, rep from * to last 6 sts, inc 1, k5. (92 sts)

Work in stocking stitch in MC until piece measures 42cm from cast-on edge.

**Shape armholes:**
Cast off 6 sts at beg of next 2 rows. (80 sts)
Dec 1 st at each end of next 6 rows. (68 sts)
Cont straight until armhole measures 25cm.

**Shape shoulders:**
Cast off 6 sts at beg of next 4 rows.
Cast off 7 sts at beg of next 2 rows.
Leave rem 30 sts on holder for back neck.

## FRONT
Work as for back to armhole shaping.

**Shape armholes:**
Cast off 6 sts at beg of next 2 rows. (80 sts)
Dec 1 st at each end of next 6 rows. (68 sts)

**Begin Arc Reactor Chart:**
Work 8 rows straight, then begin chart on next row, positioning centre of chart at centre 40 sts.

[Continue following chart for 32 rows]

**Shape neck:**
When armhole measures 18cm:
Next row: K23, leave centre 22 sts on holder, join new yarn and k23.
Working both sides simultaneously:
Dec 1 st at neck edge every row 6 times. (17 sts each side)
Cont straight until armhole matches back.

**Shape shoulders:**
Cast off 6 sts at beg of next 2 rows (at armhole edge).
Cast off rem 7 sts.

## ARC REACTOR CHART
```
[Chart shows 32-row × 40-stitch circular design]
Key:
□ = MC (red)
■ = CC1 (gold) 
● = CC2 (blue)
○ = CC3 (white)
```

Row 16 (centre): K14 MC, k1 CC3, k1 CC2, k8 CC3, k1 CC2, k1 CC3, k14 MC

**Chart Notes:** The arc reactor is worked as a circle with concentric rings. Use intarsia method, twisting yarns at colour changes.

## SLEEVES (Make 2)
Using 4.0mm needles and MC, cast on 42 sts.
Work in 1×1 rib for 6cm.

Change to 4.5mm needles.
Next row (inc row): K2, inc 1, k to last 2 sts, inc 1, k2. (44 sts)

**Colour Pattern for Sleeves:**
Work 10 rows MC.
Work 4 rows CC1.
Work 6 rows MC.
Cont in MC, inc 1 st at each end of 8th row and every following 8th row until 66 sts.

Cont straight until sleeve measures 46cm from cast-on.

**Shape sleeve cap:**
Cast off 6 sts at beg of next 2 rows.
Dec 1 st at each end of every RS row 16 times.
Cast off 3 sts at beg of next 4 rows.
Cast off rem 16 sts.

## NECKBAND
Join right shoulder seam.
Using 4.0mm needles and MC, pick up and knit:
- 15 sts down left front neck
- 22 sts from front holder  
- 15 sts up right front neck
- 30 sts from back holder
(82 sts total)

Work in 1×1 rib for 3cm.
Cast off in rib.

## MAKING UP
1. Join left shoulder and neckband seam
2. Set in sleeves, matching centre of sleeve cap to shoulder seam
3. Join side and sleeve seams
4. Work duplicate stitch details on arc reactor using CC2 and CC3 for additional definition
5. Weave in all ends securely

**Finishing Notes:** 
- Steam lightly avoiding ribbing
- The intarsia sections may need gentle blocking to even out tension
- Consider adding small duplicate stitch details to enhance the technological appearance

**Advanced Techniques Used:**
- Intarsia colourwork
- Complex shaping coordination  
- Chart reading
- Duplicate stitch finishing

This pattern creates a sophisticated interpretation of Ironman's iconic appearance suitable for advanced knitters comfortable with colourwork techniques.
