Planning
1. **Design Strategy**: The core request is for a boomerang shawl, started from one tip, featuring specific increase/decrease rates, clean edges, and a Mistake Rib body. The template's general instructions for a "Triangular Lace Shawl" with a "Garter stitch body" and "center top down" construction will be overridden by the user's specific design requirements. The "longest side" (190 cm) will be interpreted as the length along the continuously increasing edge, determining the total number of rows.
2. **Construction Plan**:
* **Start**: Cast on 3 stitches, forming the initial tip.
* **Edges**: Defined as `sl1pwyf` at the start of every row and `K1` at the end of every row for a clean, non-curling edge.
* **Increase Side (Side A)**: 1 stitch increased in *every* row, placed immediately after the first border stitch (`Sl1pwyf, M1L`). The M1L will integrate into the Mistake Rib pattern.
* **Decrease Side (Side B)**: 1 stitch decreased in *every second* row, placed immediately before the last border stitch (`... ssk` on RS, `... k2tog` on WS, `K1`).
* **Body Pattern**: Mistake Rib. This will be worked on all stitches between the increased stitch (on Side A) and the decreased stitch (on Side B). The Mistake Rib pattern chosen is a K2, P2 repeat on RS, and a shifted P1, K2, P2 repeat on WS. New stitches from M1L will be worked into the Mistake Rib pattern on the subsequent row.
* **Growth**: The shawl will grow by +1 stitch on every row (due to Side A increase) and -1 stitch on every second row (due to Side B decrease). This results in a net increase of +0.5 stitches per row on average.
3. **Quality Assurance**:
* **Mistake Rib Integration**: This is the most complex aspect. Instructions will specify how the Mistake Rib is continued and how newly added stitches or decreased stitches are handled within the pattern repeat. The pattern will be established gradually over the initial rows.
* **Edge Definition**: Ensure the "clean and neat border stitches" are consistently applied and distinguished from the main body pattern.
* **Stitch Counts**: All calculations for stitch and row counts will be verified for consistency with the tension (gauge) and desired finished measurements.
* **Terminology**: Strict adherence to UK English spelling, metric measurements first, and standard UK knitting abbreviations.
4. **Final Calculations**:
* **Tension (Gauge)**: Assuming a standard tension for fingering weight on 4.00 mm needles: 22 stitches and 30 rows = 10 cm (4 inches) in Mistake Rib, after blocking.
* **Longest Edge**: 190 cm (75 inches). This edge is formed by the continuously increasing Side A.
* **Total Rows**: 190 cm * (30 rows / 10 cm) = 570 rows.
* **Average Stitch Increase**: (1 stitch/row - 1 stitch/2 rows) = 0.5 stitches/row.
* **Final Stitch Count**: 3 (initial CO) + (570 rows * 0.5 stitches/row) = 3 + 285 = 288 stitches.
* **Maximum Width**: 288 stitches / (2.2 stitches/cm) = approx. 130.9 cm (51.5 inches).
* **Yarn Estimate**: Approx. 1200-1500 metres (1300-1650 yards) of fingering weight yarn will be estimated for a shawl of this size.
Verification
[PRE-FLIGHT CHECKS]
Before generating the pattern, verify your plan against the requirements:
1. **Completeness**: Yes, all required sections from the template structure will be included, with content adapted for the boomerang shawl. Blocking instructions will be included.
2. **Consistency**: Yes, the calculated stitch count (288 sts) and total rows (570 rows) are consistent with the chosen tension (22 sts & 30 rows / 10cm) and the target longest edge (190cm) and increase/decrease rates (net +0.5 sts/row). The maximum width (131cm) is also consistent with the final stitch count.
3. **Constraints**: Yes, all user-specific requests have been addressed: boomerang shape, 1 st inc one side every row, 1 st dec other side every second row, Mistake Rib body, clean border stitches, started with 3 sts from one tip, fingering weight yarn, 4.00 mm needles, 190 cm longest side. The difficulty level is set to Intermediate due to the dynamic nature of the Mistake Rib.
4. **Safety**: The math calculations for stitches and rows appear sound based on the chosen gauge and interpretation of the longest side. The detailed instructions for the Mistake Rib will ensure pattern integrity as the stitch count changes.

# Boomerang Shawl
This elegant shawl begins with just a few stitches at one tip and gracefully expands into a gentle boomerang shape. The main body features a sophisticated Mistake Rib texture, framed by neat, clean edges. The rhythmic increases and decreases create an interesting asymmetric drape, perfect for wrapping or styling.
**DIFFICULTY LEVEL:** Intermediate
**FINISHED MEASUREMENTS:**
* **Longest Edge:** approx. 190 cm (75 inches)
* **Maximum Width:** approx. 131 cm (51.5 inches)
**YARN:**
* Fingering weight yarn, approx. 1200-1500 metres (1300-1650 yards).
*(For example, 3-4 skeins of a typical 400m/100g fingering yarn.)*
**NEEDLES:**
* 4.00 mm (US 6) circular needles, at least 100 cm (40 inches) long, to accommodate the increasing number of stitches.
**TENSION (GAUGE):**
* 22 stitches and 30 rows = 10 cm (4 inches) in Mistake Rib, after blocking.
*Take time to check your tension. Adjust needle size if necessary to obtain the correct tension.*
**TERMINOLOGY & ABBREVIATIONS:**
* This pattern uses UK English spelling and metric measurements first.
* **k:** knit
* **p:** purl
* **sl1pwyf:** slip 1 stitch purlwise with yarn in front
* **M1L:** make one left (insert left-hand needle under horizontal strand between stitches from front to back, knit into the back loop)
* **ssk:** slip, slip, knit (slip next 2 stitches knitwise to right-hand needle, insert left-hand needle into fronts of both slipped stitches from left, knit them together) – *leans left*
* **k2tog:** knit 2 together (knit 2 stitches together as one) – *leans right*
* **rep:** repeat
* **st(s):** stitch(es)
* **RS:** right side
* **WS:** wrong side
**NOTES:**
* This shawl is worked flat from one tip.
* The "border stitches" refer to the first and last stitch of every row. They are worked as `sl1pwyf` at the beginning and `K1` at the end of every row, creating a neat chain edge.
* Increases are worked on one side (Side A) in every row. Decreases are worked on the other side (Side B) in every second row. This creates the asymmetric boomerang shape.
* The Mistake Rib pattern is worked on all stitches between the increase/decrease actions and the border stitches. New stitches created by M1L will be incorporated into the Mistake Rib pattern on the following row.
**MISTAKE RIB PATTERN (Worked on Body Stitches):**
The Mistake Rib pattern is established as follows for the body stitches (all stitches between the M1L/decrease and the border K1):
* **RS Rows:** (K2, P2) repeat across the body stitches. The first 2 body stitches should begin with K2. Adjust the last few stitches as needed to maintain the K2, P2 sequence as far as possible.
* **WS Rows:** (P1, K2, P2) repeat across the body stitches, ending with K2, P1 if the stitch count allows for the final repeat. The first body stitch should begin with P1. Adjust the last few stitches as needed.

**INSTRUCTIONS:**
**CAST ON:**
Using 4.00 mm needles, cast on 3 stitches.
*(Initial Stitch Count: 3 sts)*
**SETUP ROW (WS):**
Purl to end. (3 sts)
**INITIAL ROWS (Establishing shape and pattern):**
Work these first 4 rows to begin the shawl's shape and integrate the Mistake Rib.
**Row 1 (RS - Inc Row):** Sl1pwyf, M1L, K to end. (4 sts)
*(After Sl1pwyf and M1L, you have 2 stitches remaining. K them. So the body is K2)*
**Row 2 (WS - Inc Row):** Sl1pwyf, M1L, P to end. (5 sts)
*(After Sl1pwyf and M1L, you have 3 stitches remaining. P them. So the body is P3)*
**Row 3 (RS - Inc Row):** Sl1pwyf, M1L, K to end. (6 sts)
*(After Sl1pwyf and M1L, you have 4 stitches remaining. K them. So the body is K4)*
**Row 4 (WS - Inc & Dec Row):** Sl1pwyf, M1L, P to last 3 sts, k2tog, K1. (6 sts)
*(After Sl1pwyf and M1L, you have 4 stitches remaining. P2. Now there are 2 stitches remaining before the last K1. K2tog (these two stitches). So the body is P2, k2tog)*
*(Current Stitch Count: 6 sts)*
---
**MAIN BODY (Repeat Section):**
The Mistake Rib pattern will now be worked on the body stitches. Repeat the following 4-row sequence until you have completed **570 rows in total** from the cast on edge, or until the longest edge measures approximately 190 cm (75 inches).
*(Total rows required: 570. Initial 4 rows worked. Remaining rows: 566.)*
*(Total stitches will increase by 2 stitches every 4 rows.)*
**Row 5 (RS - Inc Row):** Sl1pwyf, M1L, work Mistake Rib to last st, K1. (1 st increased; Current Stitch Count: 7 sts)
*(For Mistake Rib: The 1st st after M1L will be the 1st st of the (K2, P2) repeat. So, after M1L, [K2, P2] across body stitches as established, K1.)*
**Row 6 (WS - Inc & Dec Row):** Sl1pwyf, M1L, work Mistake Rib to last 3 sts, k2tog, K1. (No net stitch change; Current Stitch Count: 7 sts)
*(For Mistake Rib: The 1st st after M1L will be the 1st st of the (P1, K2, P2) repeat. So, after M1L, P1, [K2, P2] across body stitches as established, working k2tog before the final K1.)*
**Row 7 (RS - Inc Row):** Sl1pwyf, M1L, work Mistake Rib to last st, K1. (1 st increased; Current Stitch Count: 8 sts)
**Row 8 (WS - Inc & Dec Row):** Sl1pwyf, M1L, work Mistake Rib to last 3 sts, k2tog, K1. (No net stitch change; Current Stitch Count: 8 sts)
**(Continue repeating Rows 5-8 until you have completed 570 rows from the beginning. Your final stitch count will be 288 stitches.)**
*(At 570 rows, total increases will be 570 x 1 = 570. Total decreases will be 570/2 = 285. Net increase = 570 - 285 = 285. Initial stitches = 3. Final stitches = 3 + 285 = 288 sts.)*

**FINISHING:**
**Cast Off Row (RS):**
Knit across, casting off stitches as you go. Cast off loosely to match the tension of the blocked shawl.
**Final Stitch Count Check:** Ensure you have 288 stitches before casting off.
**Weave in all loose ends.**

**BLOCKING:**
Blocking is crucial for this shawl to open up the Mistake Rib pattern and achieve the final dimensions and drape.
1. Gently hand wash your shawl in lukewarm water with a wool-friendly detergent. Avoid agitation.
2. Rinse thoroughly until the water runs clear.
3. Carefully squeeze out excess water, supporting the shawl's weight. Do not twist or wring.
4. Lay the shawl flat on a clean towel and roll it up to absorb more water. You can gently step on the towel roll.
5. Unroll the shawl and transfer it to a flat, clean surface suitable for blocking (e.g., foam blocking mats, carpet).
6. Gently stretch and shape the shawl to the desired boomerang dimensions, paying attention to the longest edge (190 cm / 75 inches) and maximum width (131 cm / 51.5 inches).
7. Pin the edges securely, using rust-proof pins, to hold the shape while drying. Pay special attention to opening up the Mistake Rib texture.
8. Allow the shawl to dry completely, which may take 24-48 hours depending on humidity.
9. Once dry, unpin your beautiful Boomerang Shawl and enjoy!
