AI Thinking Process
Planning
1. **Design Strategy**: The Thea Sweater is a relaxed, boxy drop-shoulder pullover in worsted-weight yarn with a classic boatneck β the easiest neckline requiring no shaping. Clean stocking stitch body with ribbed hems and cuffs for a beginner-friendly project.
2. **Construction Plan**: Worked flat in two rectangles (Back and Front), shoulders joined by seaming, then sleeves picked up along the straight armhole edge and worked top-down to the cuff.
3. **Quality Assurance**:
- Ensure positive ease (boxy fit β 15β20 cm / 6β8 in) is reflected in finished bust.
- Pick-up rate along armhole must match tension (3 sts per 4 rows) so sleeve sits flat.
- Boatneck opening must be wide enough to fit over the head but balanced with shoulder seam width.
4. **Final Calculations**:
- Tension: 18 sts & 24 rows = 10 cm in st st (5 mm needles).
- Cast-on (Back/Front) per size: 90 / 99 / 108 / 117 / 126 sts β finished bust β 100 / 110 / 120 / 130 / 140 cm.
- Body length to shoulder β 60 / 61 / 62 / 63 / 64 cm.
- Armhole depth β 22 / 23 / 24 / 25 / 26 cm β pick up β 80 / 84 / 88 / 92 / 96 sts.
- Boatneck: shoulder = 27 sts each side, centre neck = 36 / 45 / 54 / 63 / 72 sts left open.
Verification
[PRE-FLIGHT CHECKS]
1. **Completeness**: Includes Materials, Tension, Sizing, Back, Front, Shoulder Join, Sleeves, Neckband, Finishing. β
2. **Consistency**: 90 sts Γ· 18 sts/10 cm = 50 cm width Γ 2 = 100 cm bust (size S). β Shoulder check: 27 + 36 + 27 = 90. β Sleeve pick-up 80 sts Γ· 18 = 44.4 cm β 2 Γ 22 cm armhole depth. β
3. **Constraints**: Worsted weight, UK terminology, metric-first, boatneck, boxy drop-shoulder β all addressed. β
4. **Safety**: All stitch counts divisible appropriately; rib multiples (k1, p1) require even numbers β all cast-on counts are even. β

## CONSTRUCTION NOTES
The Thea is a **drop-shoulder pullover** β the boxiest, most relaxed style.
1. **Back** and **Front** are worked flat as plain rectangles with **no armhole shaping**.
2. **Shoulders** are joined by seaming the outer edges, leaving the centre stitches open for the **boatneck**.
3. **Sleeves** are picked up from the straight vertical armhole edge and worked **down to the cuff** β no sleeve cap shaping.

## STITCH COUNT REFERENCE
| | S | M | L | XL | 2XL |
|---|---|---|---|----|-----|
| Back/Front CO sts | 90 | 99 | 108 | 117 | 126 |
| Body length to shoulder (cm) | 60 | 61 | 62 | 63 | 64 |
| Shoulder sts (each side) | 27 | 27 | 27 | 27 | 27 |
| Centre neck sts (held) | 36 | 45 | 54 | 63 | 72 |
| Armhole depth (cm) | 22 | 23 | 24 | 25 | 26 |
| Sleeve PU sts | 80 | 84 | 88 | 92 | 96 |
| Sleeve length to cuff (cm) | 44 | 44 | 45 | 45 | 46 |
*Note: rib is a k1, p1 multiple of 2 β all cast-on counts are even/odd as required; centre-neck counts are balanced so shoulders remain equal (27 + centre + 27 = total).*
*Validation S: 27 + 36 + 27 = 90 β. M: 27 + 45 + 27 = 99 β. L: 27 + 54 + 27 = 108 β. XL: 27 + 63 + 27 = 117 β. 2XL: 27 + 72 + 27 = 126 β.*
---
## BACK
Using **4 mm needles**, CO **90 (99, 108, 117, 126)** sts.
**Note:** For a clean k1, p1 rib, begin/end as below:
- For even counts (S, L, 2XL): *k1, p1; rep from * to end.
- For odd counts (M, XL): k1, *p1, k1; rep from * to end (rib starts and ends with k1).
Work in k1, p1 rib for **6 cm (2Β½ in)**.
Change to **5 mm needles**.
Work in st st (k on RS, p on WS) until piece measures **60 (61, 62, 63, 64) cm** from cast-on edge, ending with a WS row.
*Math check (S): 90 sts Γ· 18 sts per 10 cm = 50 cm width. Width Γ 2 (front + back) = 100 cm finished bust β.*
**Shoulders & Neck:**
- BO all **90 (99, 108, 117, 126)** sts loosely, OR
- Place sts on holders if joining with three-needle bind-off (recommended for tidy shoulders): the outer **27 sts** at each side are the shoulders; the centre **36 (45, 54, 63, 72)** sts form the back neck.
Set aside.
---
## FRONT
Work exactly as for the **Back**, including length.
Because this is a **boatneck**, the Front requires **no neck shaping** β it is identical to the Back.
BO or hold sts as for the Back: outer **27 sts** each side = shoulders; centre **36 (45, 54, 63, 72)** sts = front neck.
---
## JOINING THE SHOULDERS
With RS together (or using three-needle bind-off with 5 mm needle):
1. Join the **27 shoulder sts** of the right Front to the **27 shoulder sts** of the right Back.
2. Repeat for the left shoulder (**27 sts**).
3. **Leave the centre 36 (45, 54, 63, 72) sts of Front and Back unworked** β this forms the boatneck opening.
*Boatneck opening width (S): 36 sts Γ· 18 = 20 cm (8 in) β comfortably fits over the head.*
---
## SLEEVES (worked top-down)
Lay the joined body flat and measure **down from the shoulder seam** along the side edge: **22 (23, 24, 25, 26) cm** on each side of the seam, marking the total armhole depth.
With **5 mm needles** and RS facing, beginning at the underarm, **PU 80 (84, 88, 92, 96)** sts evenly along the straight armhole edge (centre the pick-up on the shoulder seam).
*Pick-up rate: 3 sts per 4 rows. PU 80 sts (S) over an armhole edge of approx. 44 cm (2 Γ 22 cm) β 80 sts Γ· 18 = 44.4 cm β.*
Work in st st, beginning with a **purl (WS)** row.
**Sleeve shaping (decrease):**
Work 6 rows straight.
**Decrease row (RS):** k1, k2tog, k to last 3 sts, ssk, k1. *(2 sts decreased)*
Rep the decrease row **every 8th row** a total of **14 (15, 16, 17, 18)** times.
Stitch count after decreases:
- S: 80 β 28 = **52 sts**
- M: 84 β 30 = **54 sts**
- L: 88 β 32 = **56 sts**
- XL: 92 β 34 = **58 sts**
- 2XL: 96 β 36 = **60 sts**
Continue straight until sleeve measures **40 (40, 41, 41, 42) cm** from the pick-up edge, ending with a WS row.
**Cuff:**
Change to **4 mm needles**.
Work in k1, p1 rib for **4 cm (1Β½ in)**.
BO loosely in rib.
Total sleeve length β **44 (44, 45, 45, 46) cm** β.
Work the **second sleeve** identically on the opposite armhole.
---
## NECKBAND (Boatneck Finish)
The boatneck can be finished simply or with a neat ribbed band.
**Optional ribbed band (recommended):**
With **4 mm needles** and RS facing, beginning at one shoulder seam, **PU and k** sts evenly all around the neck opening:
- PU the **36 (45, 54, 63, 72)** front-neck sts + **36 (45, 54, 63, 72)** back-neck sts = **72 (90, 108, 126, 144)** sts total.
- Place a marker and join to work in the round.
Work in k1, p1 rib for **2.5 cm (1 in)**.
BO loosely in rib.
*Total neckband counts are even (multiples of 2) β k1, p1 rib joins cleanly in the round β.*
---
## FINISHING
1. **Seam the side seams**: with RS together, seam from the cuff edge down the underarm, then continue down the body side to the hem. Use mattress stitch for an invisible join.
2. Weave in all ends neatly.
3. **Block** the finished sweater to the measurements in the Stitch Count Reference table β blocking evens out the stocking stitch and sets the drop-shoulder shape.
