Raised Cable & Triple-Diamond Textured Blanket

Skill Level: Beginner (with post stitches)
Finished Size: 50" wide × 30" long (127 × 76 cm), excluding border

Materials

• Worsted weight yarn (category 4), approx. 950 yd (870 m) / 18 oz (510 g). Sample uses acrylic or wool-blend for clear stitch definition.
• Crochet hook size I/9 (5.5 mm) or size needed to obtain gauge
• Yarn needle
• Stitch markers (optional, to mark repeat edges)
• Scissors

Gauge

14 sts and 10 rows = 4" (10 cm) in pattern stitch after light steam blocking.
Make a 6" × 6" swatch: Ch 26, work Rows 1–12 of pattern, measure central 4". Adjust hook size if needed—post stitches draw in; looser tension is better than tighter.

Abbreviations (US Terms)

• ch – chain
• sc – single crochet
• dc – double crochet
• FPdc – front post double crochet
• BPdc – back post double crochet
• st(s) – stitch(es)
• rep – repeat
• RS – right side
• WS – wrong side
• sk – skip
• yo – yarn over

Special Stitches

• FPdc: Yo, insert hook from front to back to front around post of indicated st, yo and pull up loop, (yo and draw through 2 loops) twice.
• BPdc: Yo, insert hook from back to front to back around post of indicated st, yo and pull up loop, (yo and draw through 2 loops) twice.
• Cable Twist (worked over 2 sts): Sk next st, FPdc around next st, FPdc around skipped st (working in front of previous FPdc).
• Triple Diamond unit (6 sts): FPdc, dc, FPdc, dc, FPdc, dc — diamonds are formed by offsetting these raised posts over successive RS rows.

Notes

• Blanket is worked flat in turned rows.
• Turning ch-2 does not count as a stitch; always work first st into first dc/post.
• Pattern repeat is 12 stitches wide. Vertical lines and cables stay aligned; diamonds shift by 1 st every RS row to create the triple-diamond lattice.
• Keep post stitches relaxed so fabric lies flat.
• Stitch count remains 178 sts every row.
• Inline validation example: (14 reps × 12 sts) + 5 edge each side = 168 + 10 = 178 ✓

Stitch Diagram Legend

• ● = sc (border only)
• ─ = ch
• † = dc
• ╪ = FPdc
• ║ = BPdc (WS rows)
• ✕ = Cable Twist (2 crossed FPdc)
• ◆ = Diamond post (FPdc that forms diamond points)

Pattern

Foundation

Ch 180.
Row 1 (RS): Dc in 3rd ch from hook and in each ch across. (178 dc)
Row 2 (WS): Ch 2, turn; dc in each st across. (178 dc)

Row 8 (WS): Repeat Row 4. (178 sts)

Main Repeat

Repeat Rows 3–8 for pattern.
Each 6-row repeat measures approx. 2.4".
Work until piece measures 29" from foundation edge, ending after a WS row (approximately 12 full 6-row repeats = 72 rows + setup = 76 rows total).
Final stitch count still 178 ✓
Length check: 76 rows ÷ 10 rows per 4" = 30.4" ≈ 30" ✓

Border

Rnd 1: Ch 1, rotate to work down side edge; work 2 sc in each row-end along side (152 sc), 3 sc in corner, sc in each foundation ch across bottom (178 sc), 3 sc in corner, 2 sc in each row-end along other side (152 sc), 3 sc in corner, sc in each st across top (178 sc), 3 sc in last corner; join with sl st to first sc. (670 sc)
Rnd 2: Ch 1, sc in each sc around, working 3 sc in each corner sc; join. Fasten off.

Finishing

1. Weave in all ends securely with yarn needle.
2. Blocking (essential for raised texture): Steam block—hover iron over fabric or use steam blocker; pin to exact 50" × 30" dimensions without crushing posts. Allow to dry completely. Do not wet-block if using acrylic.
3. Optional: Add fringe or tassels to short ends if desired.

Care

Machine wash gentle cold, tumble dry low (acrylic) or hand wash and lay flat (wool blend).

Enjoy your raised cable & triple-diamond blanket! The vertical lines keep the cables crisp while the shifting diamonds add rhythmic texture—perfect for a first post-stitch project.
