## INSTRUCTIONS

### PART 1: MAIN HULL PLATES (Make 2)
*Worked flat in rows. One is the Top Hull, one is the Bottom Hull.*

**Foundation:** With MC, ch 2.
**Row 1 (RS):** 2 dc in 2nd ch from hook, turn. `[1 st + 1 inc = 2 sts]`
**Row 2:** Ch 1, dc in each st across, turn. `[2 sts]`
**Row 3:** Ch 1, inc in first st, dc to last st, inc in last st, turn. `[2 sts + 2 inc = 4 sts]`
**Row 4:** Ch 1, dc in each st across, turn. `[4 sts]`
**Row 5:** Ch 1, dc in each st across, turn. `[4 sts]`
*Note: We are increasing every 3rd row to create a long, sharp dagger shape.*

**Row 6:** Ch 1, inc in first st, dc to last st, inc in last st, turn. `[4 sts + 2 inc = 6 sts]`
**Rows 7-8:** Ch 1, dc in each st across, turn. `[6 sts]`
**Row 9:** Ch 1, inc, dc to last st, inc, turn. `[6 sts + 2 inc = 8 sts]`
**Rows 10-11:** Ch 1, dc in each st across, turn. `[8 sts]`

*Pattern Logic Check: Continues increasing by 2 sts every 3rd row.*

**Rows 12-60:** Continue the pattern of [One Increase Row followed by Two Even Rows].
*   **Row 12 (Inc):** 10 sts
*   **Row 15 (Inc):** 12 sts
*   ...
*   **Row 60 (Inc):** `[40 sts + 2 inc = 42 sts]`

**Row 61:** Ch 1, dc in each st across. `[42 sts]`
**Row 62:** Ch 1, dc in each st across. `[42 sts]`
**Row 63:** Ch 1, inc, dc to last st, inc. `[42 sts + 2 inc = 44 sts]`

*Stop here for Bottom Hull. Fasten off.*
*For Top Hull only: Do not fasten off. Work a border of dc evenly around the two long edges of the triangle (3 dc in the nose tip) to smooth the edge for sewing. Fasten off.*

### PART 2: THE TRENCH (Side Walls)
*This strip connects the top and bottom plates and creates the "thick" look of the ship.*

With MC, ch 5.
**Row 1:** dc in 2nd ch from hook and each ch across, turn. `[4 sts]`
**Rows 2-130:** Ch 1, dc in each st across, turn. `[4 sts]`
*Note: Measure this strip against the perimeter of your Hull Plates (excluding the back/stern). Add or subtract rows to match the length of the two long sides.*
Fasten off.

---

### PART 3: ENGINE PLATE (Stern)
*Worked flat. This covers the back of the ship.*

**Foundation:** With MC, ch 45 (to match the width of the hull plates at the back).
**Row 1:** dc in 2nd ch from hook and across, turn. `[44 sts]`
**Rows 2-6:** Ch 1, dc in each st across, turn. `[44 sts]`
**Row 7 (Dec):** Ch 1, dec, dc to last 2 sts, dec, turn. `[44 sts - 2 dec = 42 sts]`
**Row 8:** Ch 1, dc across. `[42 sts]`
**Row 9 (Dec):** Ch 1, dec, dc to last 2 sts, dec. `[42 sts - 2 dec = 40 sts]`
**Row 10:** Ch 1, dc across. `[40 sts]`
Fasten off.

---

### PART 4: COMMAND TOWER (Bridge)
*The distinctive T-shaped tower.*

**The Neck (Base):**
With MC, ch 16. Join to form a loop (ensure not twisted).
**Rnd 1:** Ch 1, dc in each st around, join with sl st. `[16 sts]`
**Rnds 2-4:** Ch 1, dc around, join. `[16 sts]`

**The Head (Upper Bridge):**
*Worked flat on top of the Neck.*
**Row 1:** Flatten the loop. Work 8 dc across the top opening (going through both layers to close it), turn. `[8 sts]`
**Row 2 (Expansion):** Ch 1, *inc*, repeat 8 times, turn. `[16 sts]`
**Row 3:** Ch 1, *1 dc, inc*, repeat across, turn. `[16 sts + 8 inc = 24 sts]`
**Rows 4-6:** Ch 1, dc across, turn. `[24 sts]`
**Row 7:** Ch 1, dc in BLO across. `[24 sts]` (Creates a sharp fold edge).
**Row 8:** Ch 1, *1 dc, dec*, repeat across. `[24 sts - 8 dec = 16 sts]`
**Row 9:** Ch 1, dec across. `[8 sts]`

## ASSEMBLY (TECHNICAL)

1.  **Structural Reinforcement (CRITICAL):**
    *   Trace the *Top Hull* triangle onto plastic canvas or stiff cardboard. Cut it out 2mm smaller than the crochet piece.
    *   Repeat for the *Bottom Hull*.
    *   *Without this step, the nose will curl upwards.*

2.  **Hull Assembly:**
    *   Take the *Trench* strip. Pin it to the edges of the *Bottom Hull* (Starting at back left corner, going to the nose tip, bending it sharply, and coming down the right side).
    *   Sew the Trench to the Bottom Hull using a whipstitch.
    *   Insert the Bottom Hull stiffener.
    *   Insert the Top Hull stiffener against the WS of the Top Hull crochet piece.
    *   Sew the *Top Hull* to the top edge of the Trench strip.
    *   *Stuffing:* Stuff lightly as you go. Do not overstuff the nose; keep it flat and sharp. The stiffeners provide the shape, the stuffing just prevents collapsing.

3.  **Stern Assembly:**
    *   Sew the *Engine Plate* to the open back of the wedge. Ensure the wider edge is at the top. Stuff the main body firmly before closing the final edge.

4.  **Engine Installation:**
    *   Sew the 3 *Main Engines* in a triangular formation on the Engine Plate (Two bottom, one top centre).
    *   Sew the 4 *Secondary Engines* in the gaps between the main engines.

5.  **Bridge Installation:**
    *   Sew the *Shield Generators* to the top of the Bridge Head (left and right peaks).
    *   Sew the Bridge Neck to the Top Hull, centred, approximately 3/4 of the way back from the nose.

6.  **Detailing (Surface Crochet):**
    *   Using MC yarn, slip stitch surface lines across the hull to simulate plating.
    *   Using Charcoal yarn, embroider small knots along the Trench strip to simulate weapons batteries and docking bays.

<technical_editor_notes>
*   **Math Verification:** Hull growth rate (Row 1-60) results in 42 sts width for approx 60 rows length. Assuming tension 20sts/10cm width and 22rows/10cm height: Width = 21cm, Length = 27cm. This is a ratio of 1.28, which is slightly wider than a movie-accurate Star Destroyer but necessary for amigurumi stability.
*   **Stitch Check:** Ensure `dc` is worked tightly. If gaps appear (stuffing visible), the hook is too large.
*   **Symmetry:** When sewing the Trench, ensure the "bend" at the nose is exactly centered on the single stitch at the tip of the Hull plates to prevent twisting.
