1. **Analysis**: The user requests a beginner-friendly crochet pattern for "Alf the Alien" using worsted weight yarn. The persona is a strict Technical Editor and Designer. Key constraints: UK English spelling, Metric measurements, UK Crochet Terminology (dc instead of sc), and inline math validation.
2. **Reference Classes**:
* *Reference 1*: Classic "Amigurumi Doll" construction (Legs joined into body, continuous head) to minimize sewing for beginners.
* *Reference 2*: "Weebee" style dolls (bulbous head, pear-shaped body).
* *Reference 3*: Standard sphere mathematics (6-12-18-24 progression) for the head.
3. **Edge Cases & Failure Modes**:
* *Mode 1 (Floppy Neck)*: Head is too heavy for the neck. *Prevention*: Pattern will decrease to 18 stitches (not 12) at the neck for stability, and instructions will emphasize firm stuffing in the neck area.
* *Mode 2 (Gaps in fabric)*: Beginner uses the hook recommended on the yarn band (usually 5.0mm for worsted). *Prevention*: Explicitly state to use a smaller hook (3.5mm) to create stiff fabric that hides stuffing.
* *Mode 3 (Confusing Leg Join)*: Joining legs can be tricky for beginners. *Prevention*: Detailed, step-by-step text instruction for the joining round.
4. **Plan**:
* **Gauge/Tension**: Tight tension is key; exact dimensions aren't critical but consistency is.
* **Dimensions**: Approx 20cm tall.
* **Construction**: Feet -> Legs -> Body -> Head (one piece). Arms and Antennae made separately and attached.
[PRE-FLIGHT CHECKS]
1. **Completeness**: Title, Materials, Tension, Abbreviations, Pattern (Legs, Body, Head, Arms, Eyes, Antennae), Finishing included.
2. **Consistency**: UK Terms used (dc for single crochet). Metric measurements used.
3. **Constraints**: Inline math validation `[...]` prepared for every row with stitch count changes.
4. **Safety**: Checked math for the leg join (12+12=24) and head expansion (18 to 42).
# Alf the Alien - Amigurumi Pattern
**Difficulty:** Beginner
**Terminology:** UK Crochet Terms (Note: UK 'dc' = US 'sc')
**Finished Size:** Approximately 20 cm tall
## Description
Alf is a friendly extraterrestrial with a pear-shaped body and a large head. This project is designed for beginners, minimizing sewing by crocheting the legs, body, and head in one continuous piece.
## Materials
* **Yarn:** Worsted weight (Aran/10 ply).
* Colour A (Green): Approx 70g / 120m
* Colour B (Black or Dark Grey): Small amount for eyes
* **Hook:** 3.50 mm (making the fabric tight to prevent stuffing showing through).
* **Notions:** Toy stuffing (polyester fibre fill), tapestry needle, stitch marker, scissors.
## Tension (Gauge)
Tension is not critical for this toy, but stitches must be tight.
**Check:** 5 rounds of a standard circle should measure approx 4.5 cm diameter.
## Abbreviations (UK Terms)
* **ch:** chain
* **dc:** double crochet (equivalent to US single crochet)
* **st(s):** stitch(es)
* **inc:** increase (work 2 dc into the same stitch)
* **inv dec:** invisible decrease (insert hook into front loop of first st, then front loop of second st, yarn over, pull through 2 loops, yarn over, pull through final 2 loops)
* **sl st:** slip stitch
* **[...]:** Total stitch count at end of round
## Special Notes
* Work in continuous spirals. Do not join rounds with a slip stitch unless instructed.
* Use a stitch marker to mark the first stitch of every round.
* **Verification Math:** The math for every stitch change is provided in brackets like this: `[Math: start + inc = end]`.

## Instructions
### Legs (Make 2)
*Make the first leg and fasten off. Make the second leg but **DO NOT** fasten off; you will continue into the body.*
**Rnd 1:** Using Colour A, start 6 dc into a Magic Ring (or ch 2, 6 dc in 2nd ch from hook). [6 sts]
**Rnd 2:** (Inc) 6 times. `[Math: 6 + 6 = 12 sts]`
**Rnd 3 - Rnd 6 (4 rounds):** Dc in each st around. [12 sts]
*Fasten off Leg 1. Repeat Rnds 1-6 for Leg 2. Do not fasten off Leg 2.*
### Body (Continuing from Leg 2)
**Rnd 7 (Joining):** Dc in next 12 sts of Leg 2, then jump to Leg 1 and dc in the 12 sts of Leg 1. `[Math: 12 (leg 2) + 12 (leg 1) = 24 sts]`
*Use the yarn tail from Leg 1 to sew the small gap between the legs closed tight.*
**Rnd 8:** (3 dc, inc) 6 times. `[Math: 24 + 6 = 30 sts]`
**Rnd 9 - Rnd 14 (6 rounds):** Dc in each st around. [30 sts]
**Rnd 15:** (3 dc, inv dec) 6 times. `[Math: 30 - 6 = 24 sts]`
**Rnd 16 - Rnd 17 (2 rounds):** Dc in each st around. [24 sts]
**Rnd 18:** (2 dc, inv dec) 6 times. `[Math: 24 - 6 = 18 sts]`
**Rnd 19:** Dc in each st around. [18 sts]
*Stuff the legs and body firmly now.*
### Head (Continuing from Body)
**Rnd 20:** (2 dc, inc) 6 times. `[Math: 18 + 6 = 24 sts]`
**Rnd 21:** (3 dc, inc) 6 times. `[Math: 24 + 6 = 30 sts]`
**Rnd 22:** (4 dc, inc) 6 times. `[Math: 30 + 6 = 36 sts]`
**Rnd 23:** (5 dc, inc) 6 times. `[Math: 36 + 6 = 42 sts]`
**Rnd 24 - Rnd 31 (8 rounds):** Dc in each st around. [42 sts]
**Rnd 32:** (5 dc, inv dec) 6 times. `[Math: 42 - 6 = 36 sts]`
**Rnd 33:** (4 dc, inv dec) 6 times. `[Math: 36 - 6 = 30 sts]`
**Rnd 34:** (3 dc, inv dec) 6 times. `[Math: 30 - 6 = 24 sts]`
*Stuff the neck area very firmly to prevent wobbling, then stuff the head.*
**Rnd 35:** (2 dc, inv dec) 6 times. `[Math: 24 - 6 = 18 sts]`
**Rnd 36:** (1 dc, inv dec) 6 times. `[Math: 18 - 6 = 12 sts]`
**Rnd 37:** (Inv dec) 6 times. `[Math: 12 - 6 = 6 sts]`
*Fasten off. Weave the yarn tail through the front loops of the remaining 6 stitches and pull tight to close.*
### Arms (Make 2)
**Rnd 1:** Using Colour A, start 6 dc into a Magic Ring. [6 sts]
**Rnd 2:** (2 dc, inc) 2 times. `[Math: 6 + 2 = 8 sts]`
**Rnd 3 - Rnd 9 (7 rounds):** Dc in each st around. [8 sts]
*Flatten the opening. Dc through both layers to close (3 or 4 sts). Fasten off, leaving a long tail for sewing.*
### Antennae (Make 2)
**Rnd 1:** Using Colour A, start 4 dc into a Magic Ring. [4 sts]
**Rnd 2:** (1 dc, inc) 2 times. `[Math: 4 + 2 = 6 sts]`
**Rnd 3:** (Inv dec) 3 times. `[Math: 6 - 3 = 3 sts]`
**Rnd 4 - Rnd 6:** Dc in each st around. [3 sts]
*Note: This is fiddly. If too difficult, simply Chain 6, sl st in 2nd ch from hook and each ch across.*
*Fasten off, leaving a tail for sewing.*
### Eyes (Make 2)
**Rnd 1:** Using Colour B (Black), start 6 dc into a Magic Ring. [6 sts]
**Rnd 2:** (Inc) 6 times. `[Math: 6 + 6 = 12 sts]`
*Sl st to first st. Fasten off, leaving a long tail for sewing. Use white yarn to stitch a small 'sparkle' highlight if desired.*
## Assembly
1. **Antennae**: Sew onto the top of the head at Rnd 31, spaced about 4 stitches apart.
2. **Eyes**: Sew onto the front of the face between Rnd 26 and Rnd 30.
3. **Arms**: Sew to the sides of the body at Rnd 19 (the neck crease).
