Needles and Hooks

• Notions: 2 locking stitch markers, tapestry needle, scissors, measuring tape, blocking tools (optional)

Gauge

• Knit (broken rib, lightly blocked): 8 sts x 12 rows = 4 in (10 cm). Stockinette reference: ≈ 9 sts x 12 rows = 4 in (10 cm)
• Crochet (hdc in back loop only): 7 sts x 6 rows = 4 in (10 cm)
• Adjust to match width; change needle/hook size if needed (see Swatching)

Abbreviations

• k = knit; p = purl; k1, p1 = 1x1 rib
• CO = cast on; BO = bind off; RS/WS = right/wrong side
• pm/sm = place/slip marker
• ch = chain; sc = single crochet; hdc = half double crochet; blo = back loop only; sl st = slip stitch

Swatching

Knit: With Needle A, CO 20 sts. Work seed border 5 sts each side with broken-rib center (see pattern rows) for 5 in (13 cm). Block and measure in center. Crochet: Ch 24; hdc blo swatch 5 in (13 cm). Adjust tool size to meet gauge.

Knit Version — Broken Rib with Seed Borders

Construction: Flat in one piece. Maintain a 10-st seed-stitch border on each edge (20 sts total). Body is broken rib that resists curling and drapes beautifully in super bulky.

Knit Cast On

• Lap: CO 80 sts
• Throw: CO 100 sts
• Oversized: CO 120 sts

Use a long-tail CO on US 15 (10.0 mm, UK Old 000). Optional: hold tail double for a cushy edge, then drop tail.

Set Up

1. Row 1 (RS): Work Seed Border 10 sts as [k1, p1] x5, pm; knit to last 10 sts, pm; work Seed Border 10 as [k1, p1] x5. This establishes borders and body.
2. Row 2 (WS): Work Seed Border 10 as [p1, k1] x5, sm; work body as [k1, p1] rib to marker, sm; work Seed Border 10 as [p1, k1] x5.

Main Pattern

1. Row 1 (RS): Seed Border 10 to marker, sm; knit all body sts to marker, sm; Seed Border 10 to end.
2. Row 2 (WS): Seed Border 10 to marker, sm; work [k1, p1] across body to marker, sm; Seed Border 10 to end.

Repeat Rows 1–2 to desired length. Approximate row counts at stated gauge: Lap ≈ 150 rows (50 in/127 cm), Throw ≈ 180 rows (60 in/152 cm), Oversized ≈ 210 rows (70 in/178 cm). Measure length relaxed on a flat surface.

Bind Off and Finishing (Knit)

1. BO in pattern on a RS row: in border, continue seed; in body, knit the knit sts and purl the purl sts as you bind off. Keep BO relaxed.
2. Weave in ends along columns of rib. Gently block: wool—soak 10–15 min, press in towel, lay flat to dimensions; acrylic—pin to size and lightly steam hover, do not touch/press.
3. Optional edge polish: single-crochet once around with 10.0 mm hook, placing ~1 sc per garter/border ridge and ~1 sc per row up the sides; or attach 6–8 in (15–20 cm) fringe every 2–3 sts along cast-on and bind-off edges.

Knit Stitch Multiple and Custom Width

Total sts = 20 border sts (10 each side) + body sts. Body must be an even number. For a custom width W inches at 2 sts per inch, choose Total CO ≈ 2 x W; if Total CO is odd, add 1 to make it even. Example: 54 in ≈ 108 sts total = 20 border + 88 body.

Crochet Version — Ribbed HDC with SC Borders

Construction: Flat in rows with 5-st single-crochet borders at each side; body worked in hdc blo for plush ribs.

Foundation Chain

• Lap: ch 70
• Throw: ch 88
• Oversized: ch 106

Hook: US N/P-15 (10.0 mm); adjust up to US P/Q (15.0 mm) if fabric is tight.

Set Up Row (WS)

Work 1 sc in 2nd ch from hook and in each ch across; turn. You now have one row of sc and the correct stitch count for your size.

Main Pattern (Crochet)

1. Row 1 (RS): Sc across first 5 sts for border; hdc blo across to last 5 sts; sc across last 5 sts; turn.
2. Row 2 (WS): Repeat Row 1, keeping borders in sc through both loops and body in hdc blo.

Repeat to length: Lap 50 in (127 cm), Throw 60 in (152 cm), Oversized 70 in (178 cm). If your row height differs, measure as you go.

Edging and Finish (Crochet)

1. Optional round of sc evenly around blanket with 10.0–12.0 mm hook, working 3 sc in each corner. Keep edges relaxed.
2. Weave in ends securely. Block lightly as fiber allows.

Alternative Textures (Knit)

• All Garter: RS and WS knit across the body; keep 10-st seed borders. CO remains the same.
• Chunky Basketweave: Body multiple of 12 + 0; work 6 rows of [k6, p6], then 6 rows of [p6, k6]. Keep 10-st seed borders; choose a CO so body is a multiple of 12.

Adjustments

• Length: Add or subtract repeats; plan 12–18 yd (11–16 m) per inch of length change for knit, 10–15 yd (9–14 m) for crochet (super bulky).
• Width: Change total CO/ch by 2 sts for knit or by 2 ch for crochet to keep symmetry.
• Loft vs. drape: Go up to US 17 (12.0 mm) or US P/Q (15.0 mm) for airier fabric; down to US 13 (9.0 mm, UK Old 00) or US M/N (9.0 mm) for denser fabric.

Troubleshooting

• Wavy edges: Your borders may be looser; tighten tension on border sts or drop 1–2 needle/hook sizes for borders only.
• Too narrow/wide: Measure after 6–8 in (15–20 cm); adjust by adding/removing body sts in multiples of 2 (knit) or chains in multiples of 2 (crochet).
• Rowing out (knit): Use a needle one size smaller for purl rows or try wooden needles to stabilize tension.

Care

Wool/wool blends: Hand wash cool, lay flat. Superwash: Machine gentle cool in a bag, lay flat. Acrylic/cotton: Machine gentle cool, lay flat to prevent stretching. Always follow yarn label.

Tools and Sizes Quick Reference

• US 13 (9.0 mm) ≈ UK Old 00
• US 15 (10.0 mm) ≈ UK Old 000
• US 17 (12.0 mm) ≈ UK Old n/a
• Crochet: US N/P-15 (10.0 mm), US P/Q (15.0 mm)

Yarn Planning Example (Throw Size)

Target 900–1,050 yd (823–960 m). If using 100 g balls ≈ 55 yd/50 m, you will need about 17–20 balls (1,700–2,000 g). If using 200 g skeins ≈ 109 yd/100 m, plan 9–10 skeins.
