Planning

1. **Design Strategy**: A cosy chunky granny square blanket in UK terms, aimed at beginners. It uses classic 3-tr clusters worked in rounds, with a single colour per square to keep things simple (an optional colour change is noted). The squares are joined with whip stitch, the easiest joining method for beginners, and finished with a simple 2-round border. 2. **Construction Plan**: Make 30 identical 6-round granny squares, whip stitch them together into a 5 × 6 grid, then work a dc and tr border around the whole blanket. 3. **Quality Assurance**: - Keep stitch counts at the corners consistent (ch 2 corner spaces) so the squares stay square. - Check tension, because bulky yarn varies widely. - Line up the corners and the right side of each square before joining so the seams sit flat. 4. **Final Calculations**: - Tension: Rounds 1–3 = 10 cm square using a 7 mm hook. - Each round adds 1 cluster per side. - Round n has n+1 clusters per side, except Round 1, which has 1 cluster per side. - Round 6 has 6 clusters per side, 24 clusters in total = 72 tr. - Finished square: 20 cm. - Blanket before border: 100 × 120 cm. - With a 2-round border (about 2.5 cm per side), the finished blanket measures about 105 × 125 cm.

Verification

1. **Completeness**: Squares, joining method (whip stitch) and border are all included. 2. **Consistency**: - Round 1: 4 clusters (1 per side). - Round 2: corner clusters only, 2 per side, 8 clusters. - Round 3: 3 per side, 12 clusters. - Round 4: 4 per side, 16 clusters. - Round 5: 5 per side, 20 clusters. - Round 6: 6 per side, 24 clusters = 72 tr ✓ - Square size: 10 cm at Round 3, roughly 3.3 cm per round, so about 20 cm at Round 6 ✓ 3. **Constraints**: Chunky yarn, UK terms, beginner level, metric measurements first ✓ 4. **Safety (border count)**: - Each square edge has 18 tr plus corner spaces. - Border Round 1 works 20 dc per square edge (1 dc in each of the 18 tr, plus 1 dc in each corner/seam space). - Short edge: 5 squares × 20 = 100 dc. Long edge: 6 × 20 = 120 dc. - Corners: 3 dc in each blanket corner space. 5. **Fix before writing**: No fixes needed.

Pattern

Chunky Cosy Granny Square Blanket

Skill level: Beginner | Terminology: UK crochet terms

Finished Size

Approximately 105 × 125 cm (41 × 49 in) including the border.

Each square: 20 cm (8 in).
30 squares, arranged 5 across × 6 down.

Materials

Yarn: Bulky/chunky weight yarn, approximately 2,000 m (2,190 yd) in total.
- Example: 20 × 100 g balls, roughly 100 m per ball.
- Each square uses about 55 m.
- Joining and the border use about 350 m.
Hook: 7 mm (US K/10.5–L/11).
Notions: Large-eye tapestry needle, scissors, stitch marker (optional).

Tension (Gauge)

Rounds 1–3 of the square measure 10 cm (4 in) square using a 7 mm hook.

If your square is larger, change to a smaller hook.
If it is smaller, change to a larger hook.

Abbreviations (UK)

ch = chain
ss = slip stitch
dc = double crochet (US single crochet)
tr = treble crochet (US double crochet)
sp = space
cluster = 3 tr worked into the same space
RS = right side

Notes

The beginning ch 3 counts as the first tr of a cluster.
The squares are worked in the round with the RS facing; do not turn.
Corner spaces are ch 2. The spaces between clusters along the sides are ch 1.
Optional colour change: To make multicoloured squares, fasten off at the end of any round. Join the new colour with a ss in any corner ch-2 sp, ch 3, and continue from that point.

Granny Square (make 30)

Ch 4, ss into the first ch to form a ring.

Round 1:

Ch 3 (counts as 1 tr), 2 tr into the ring, ch 2.
*3 tr into the ring, ch 2; repeat from * twice more.
Ss to the top of the beginning ch 3.
(4 clusters = 12 tr; 4 ch-2 corners ✓)

Round 2:

Ss into the next 2 tr and into the corner ch-2 sp.
Ch 3, (2 tr, ch 2, 3 tr) in the same sp, ch 1.
*(3 tr, ch 2, 3 tr) in the next ch-2 sp, ch 1; repeat from * twice more.
Ss to the top of the beginning ch 3.
(8 clusters = 24 tr; 2 per side ✓)

Round 3:

Ss into the next 2 tr and into the corner sp.
Ch 3, (2 tr, ch 2, 3 tr) in the same sp, ch 1.
*3 tr in the next ch-1 sp, ch 1, (3 tr, ch 2, 3 tr) in the corner sp, ch 1; repeat from * twice more.
3 tr in the last ch-1 sp, ch 1.
Ss to the top of the beginning ch 3.
(12 clusters = 36 tr; 3 per side ✓)

Rounds 4–6:

Ss into the next 2 tr and into the corner sp.
Ch 3, (2 tr, ch 2, 3 tr) in the same sp, ch 1.
*(3 tr, ch 1) in each ch-1 sp along the side, then (3 tr, ch 2, 3 tr, ch 1) in the corner sp; repeat from * twice more.
(3 tr, ch 1) in each remaining ch-1 sp.
Ss to the top of the beginning ch 3.
Each round adds 1 cluster per side:
- Round 4: 16 clusters = 48 tr (4 per side ✓)
- Round 5: 20 clusters = 60 tr (5 per side ✓)
- Round 6: 24 clusters = 72 tr (6 per side ✓; 18 tr per side ✓)

Fasten off, leaving a 50 cm tail on 15 of the squares to use for joining. Weave in all other ends. The square should measure 20 cm.

Joining (Whip Stitch)

Lay out the squares in 5 columns × 6 rows, all with the RS facing up.
Place two squares with their RS facing up, side by side.
Using the tapestry needle and yarn, whip stitch through the back loops only of the matching stitches along the edge.
- Start in the corner ch.
- Work 1 stitch in each of the 18 tr and in each ch.
- End in the opposite corner ch.
Join the squares into 6 strips of 5 squares each.
Join the strips together lengthwise, keeping the corners aligned.
Weave in all ends securely.

Join check: 5 squares × 20 cm = 100 cm wide ✓; 6 squares × 20 cm = 120 cm long ✓

Border

Round 1:

Join the yarn in any blanket corner ch-2 sp.
Ch 1, 3 dc in the same sp.
Along each edge, work 1 dc in each tr and ch-1 sp, and 1 dc in each square's corner sp at the seams.
Aim for 20 dc per square edge:
- Short edges: 5 × 20 = 100 dc.
- Long edges: 6 × 20 = 120 dc.
Work 3 dc in each blanket corner.
Ss to the first dc.
(Total: 2 × 100 + 2 × 120 + 12 corner dc = 452 dc ✓)

Round 2:

Ch 3 (counts as tr).
Work 1 tr in each dc, with 3 tr in the centre dc of each corner.
Ss to the top of the beginning ch 3.
(452 + 8 = 460 tr ✓)

Fasten off.

Finishing

Weave in all remaining ends.
Gently steam block, holding the iron above the fabric. Do not press acrylic yarns.
Finished size: about 105 × 125 cm ✓

Enjoy your cosy blanket!
