1. **Design Strategy**: - Goal: Make a beginner-friendly chibi-style doll using only basic amigurumi techniques (magic ring, sc, inc, dec, slip stitch) and simple shapes (sphere for head, short cylinder for body, small cylinders for arms/legs, half-sphere for hair/hood). - Yarn & hook: Worsted weight (4) yarn, recommended hook US F/5 - G/6 (3.5–4.0 mm). I specify 3.5 mm for a firmer fabric for stuffing. - Style choices: oversized head-to-body ratio (~1.0 head : 1.0 body) for “chibi” look, simple face (embroidered or safety eyes) and optional simple hair/hood cap. Keep pieces few and easy to sew. 2. **Construction Plan**: - Top-down, three main pieces plus small appendages: - Head: Sphere (complete closed sphere). - Body: Short cylinder (increase to match head circumference, then work even rounds and close/taper). - Arms (x2): short cylinder tubes. - Legs (x2): short cylinder tubes, slightly longer than arms. - Hair/hood: half-sphere worked as a sphere but stopped early and flattened into a cap. - Stuff pieces as you go; sew head to body with ladder stitch; pin before sewing. Use magic ring start to avoid holes. 3. **Quality Assurance**: - Potential pitfalls: - Loose fabric: use smaller hook (3.5 mm) and stuff firmly. - Uneven decreases producing flat spots on sphere: use invisible decrease technique and add stuffing gradually. - Eye placement too low/high: give clear metric placement measurement from top of head. - Verification steps included: stitch-count checks at each round, inline math validation for increases/decreases, and a size/gauge check to match expected finished dimensions. 4. **Final Calculations**: - Working gauge (crochet, worsted weight, 3.5 mm hook): 16 sc = 10.0 cm (measured across, typical amigurumi gauge for worsted on a tight 3.5 mm hook). This is used for dimension estimates below. - Head sphere equator = 24 sts (pattern rounds produce 24 sts at Rnds 4–8). Circumference = (24 sts / 16 sts) * 10.0 cm = 15.0 cm. Diameter = circumference / π = 15.0 / 3.1416 ≈ 4.77 cm. - Body circumference = 24 sts → width ≈ 4.77 cm (same as head) for balanced chibi proportions. - Body height estimate: body worked for 12 rounds. Vertical gauge estimate: 2.25 rounds per cm (≈9 rounds per 4.0 cm). So body height = 12 / 2.25 ≈ 5.33 cm. - Total finished height (head + body + legs seam allowance) ≈ 4.77 + 5.33 + 2.5 (legs and seam) ≈ 12.6 cm. Expect finished doll ≈ 11–13 cm tall (handheld chibi size).

[PRE-FLIGHT CHECKS] 1. **Completeness**: Pattern includes materials, abbreviations, full crocheted assembly instructions (sphere, cylinder, oval variants), assembly/finishing, size/gauge calculations, and a machine-knitting alternative section with bed/cast-on/tension/RC/COL-COR references plus required tools (transfer tools, ribber, weights, cast-on comb, ravel cord). OK. 2. **Consistency**: All stitch counts in rounds are validated inline. Example: Rnd 3 on sphere — starting 12 sts, pattern (sc, inc) x6 → adds 6 sts → 18 sts (12 + 6 = 18). All increase/decrease math checked. OK. 3. **Constraints**: User requested a chibi-style doll and beginner difficulty — pattern uses only basic amigurumi techniques and simple shapes per template. Yarn weight set to worsted. Machine-knitting requirements provided (as requested in template). OK. 4. **Safety**: No unsafe math operations. Eye placement and use of safety eyes flagged for age suitability (suggest embroidery for toys for small children). OK.
