Planning
1. **Design Strategy**: The user request for "small gifts for work colleagues" at a "beginner" difficulty level perfectly aligns with a simple, quick-to-make crochet coaster. This item is practical, uses minimal yarn, and is universally suitable for gifting. The design will prioritise straightforward construction and basic stitches to ensure accessibility for beginners. Worsted weight yarn is specified, offering a good balance of speed and a durable, functional finished product. All terminology will strictly adhere to UK English conventions.
2. **Construction Plan**: The coaster will be worked seamlessly in the round, starting from a Magic Ring (MR) to achieve a neat, closed centre. Treble crochet (tr, equivalent to US double crochet) will be the primary stitch, chosen for its ability to create fabric quickly while maintaining good structure for a coaster. A standard flat circle increase method (12 increases per round for tr) will be employed to ensure the coaster lays perfectly flat. Rounds will be joined with a slip stitch (sl st), and the beginning of each new round will be established with a chain-3 that counts as the first treble.
3. **Quality Assurance**:
* **Flatness and Shape**: The most critical aspect for a circular coaster is maintaining a flat, even shape. The pattern will precisely dictate 12 increases per round to prevent ruffling or cupping.
* **Clarity and Simplicity**: Instructions will be broken down clearly by round, with explicit stitch counts at the end of each round to help beginners track their progress and verify their work. Complex or unusual techniques will be avoided.
* **Terminology Consistency**: Strict adherence to UK crochet terminology (e.g., tr for US dc, dc for US sc) and UK English spelling (e.g., "colour", "centre") will be maintained throughout. Metric measurements will be prominent.
* **Beginner Accessibility**: The design focuses on repetitive stitch patterns and foundational skills, making it achievable for those new to crochet.
4. **Final Calculations**:
* **Gauge/Tension**: A target tension of 16 trebles (tr) and 9 rounds per 10 cm (4 inches) will be established as a guideline for worsted weight yarn and a 4.0 mm hook. This is crucial for achieving the correct finished dimensions.
* **Finished Dimensions**: The target finished diameter for the coaster is approximately 11.5 – 12 cm (4.5 – 4.75 inches).
* **Stitch Counts (for a 5-round coaster using tr with 12 increases per round):**
* Round 1: 12 tr
* Round 2: 24 tr (12 increases: 2 tr in each st)
* Round 3: 36 tr (12 increases: (1 tr, 2 tr in next st) x 12)
* Round 4: 48 tr (12 increases: (2 tr, 2 tr in next st) x 12)
* Round 5: 60 tr (12 increases: (3 tr, 2 tr in next st) x 12)
* **Diameter Validation**: Based on the target tension of 16 tr = 10 cm, the circumference of a 60-stitch round would be (60 stitches / 16 stitches/10cm) * 10cm = 37.5 cm. The diameter (Circumference / π) would therefore be 37.5 cm / 3.14159 ≈ 11.93 cm. This precisely meets the target finished size of 11.5 – 12 cm.
Verification
[PRE-FLIGHT CHECKS]
Before generating the pattern, verify your plan against the requirements:
1. **Completeness**: All required sections from a comprehensive pattern template (Pattern Name, Description, Skill Level, Materials, Tension, Finished Size, Abbreviations, Notes, Pattern Instructions, Finishing) will be included in the `<pattern>` output.
2. **Consistency**: The planned stitch counts for each round, the chosen gauge, and the resulting finished diameter are mathematically consistent and verified. UK English spelling, metric measurements first, and UK crochet terminology are consistently applied throughout the plan and will be in the pattern.
3. **Constraints**: The design directly addresses all user-specified constraints: it is a small, beginner-level gift suitable for colleagues, uses worsted weight yarn, and adheres to the specified UK terminology and measurement profiles.
4. **Safety**: The mathematical calculations for stitch increases in a flat circle using trebles (12 increases per round) are standard and have been cross-verified for each round. The instructions for handling the starting chain-3 as the first treble have been carefully constructed to maintain accuracy in stitch counts.

Utilising basic stitches and worked seamlessly in the round, this coaster is quick to make and perfect for a thoughtful, handmade present. Each coaster provides a delightful spot for a mug and adds a touch of handmade warmth to any desk or home. ### Skill Level Beginner ### Materials * **Yarn:** Worsted weight yarn (approx. 20g / 36 metres per coaster). Choose a durable fibre like 100% cotton or a cotton blend for absorbency and heat resistance. * **Hook:** 4.0 mm (US G/6) crochet hook * **Tapestry Needle:** For weaving in ends. * **Scissors** ### Tension (Gauge) 16 trebles (tr) and 9 rounds = 10 cm (4 inches) using 4.0 mm hook, after blocking. *It's important to check your tension to ensure your coaster will be the desired size and lay flat. If your coaster cups, your tension is too tight; if it ruffles, your tension is too loose.* ### Finished Size Approximately 11.5 cm – 12 cm (4.5 – 4.75 inches) in diameter. ### Abbreviations * **ch:** chain * **sl st:** slip stitch * **dc:** double crochet (US single crochet) * **htr:** half treble crochet (US half double crochet) * **tr:** treble crochet (US double crochet) * **st(s):** stitch(es) * **rnd(s):** round(s) * **MR:** Magic Ring * **beg:** beginning ### Notes * This pattern is worked in the round from the centre outwards. * Ch 3 at the beginning of each round counts as the first treble (tr). * Join each round with a sl st to the top of the beg ch-3. * UK crochet terminology is used throughout. ### Pattern Instructions **Coaster (make as many as desired)** **Starting with MR:** Create a Magic Ring (MR). If you are unfamiliar with the MR, alternatively: ch 4, sl st to first ch to form a ring. **Rnd 1:** Ch 3 (counts as 1st tr), 11 tr into MR. Join with sl st to top of beg ch-3. [12 sts] *(Validation: 1 ch-3 + 11 tr = 12 sts. Correct.)* **Rnd 2:** Ch 3 (counts as 1st tr), 1 tr in same st as ch-3. 2 tr in each of the next 11 sts around. Join with sl st to top of beg ch-3. [24 sts] *(Validation: 2 tr in the first st (ch-3 + 1 tr) + (11 sts x 2 tr/st) = 2 + 22 = 24 sts. Correct.)* **Rnd 3:** Ch 3 (counts as 1st tr), 2 tr in next st. *1 tr in next st, 2 tr in next st*. Repeat from * to * 11 times. Join with sl st to top of beg ch-3. [36 sts] *(Validation: 1st group (ch-3 + 2 tr in next st) creates 3 sts over 2 base sts. 11 repeats of (1 tr in next st, 2 tr in next st) creates 3 sts over 2 base sts each, so 11 * 3 = 33 sts. Total 3 + 33 = 36 sts. Base sts used: 2 + (11 * 2) = 24 sts. Correct.)* **Rnd 4:** Ch 3 (counts as 1st tr), 1 tr in next st. 2 tr in next st. *1 tr in next 2 sts, 2 tr in next st*. Repeat from * to * 11 times. Join with sl st to top of beg ch-3. [48 sts] *(Validation: 1st group (ch-3 + 1 tr in next st + 2 tr in next st) creates 4 sts over 3 base sts. 11 repeats of (1 tr in next 2 sts, 2 tr in next st) creates 4 sts over 3 base sts each, so 11 * 4 = 44 sts. Total 4 + 44 = 48 sts. Base sts used: 3 + (11 * 3) = 36 sts. Correct.)* **Rnd 5:** Ch 3 (counts as 1st tr), 1 tr in next 2 sts. 2 tr in next st. *1 tr in next 3 sts, 2 tr in next st*. Repeat from * to * 11 times. Join with sl st to top of beg ch-3. [60 sts] *(Validation: 1st group (ch-3 + 1 tr in next 2 sts + 2 tr in next st) creates 5 sts over 4 base sts. 11 repeats of (1 tr in next 3 sts, 2 tr in next st) creates 5 sts over 4 base sts each, so 11 * 5 = 55 sts. Total 5 + 55 = 60 sts. Base sts used: 4 + (11 * 4) = 48 sts. Correct.)* ### Finishing Fasten off yarn, leaving a long tail. Weave in all loose ends securely using your tapestry needle. Block the coaster lightly if desired to ensure it lays perfectly flat and to open up the stitches slightly.
