Planning

1. **Design Strategy**: Classic granny square stroller blanket in worsted weight, using 16 squares (4x4) for a pram-friendly size. Easy difficulty with traditional 4-round granny squares joined by whip stitch and finished with a simple border. 2. **Construction Plan**: Make 16 individual granny squares, block, whip stitch together in a 4x4 grid, then work a 2-round border. 3. **Quality Assurance**: - Squares must measure consistently after blocking - Corner spaces must be uniform for clean joining - Border tension must not pucker corners 4. **Final Calculations**: - Tension: 4-round granny square = 10cm x 10cm with 5mm hook - 16 squares (4 wide x 4 tall) = 40cm x 40cm before border - Border adds ~4cm = finished ~44cm x 44cm (17.5" x 17.5") — ideal stroller size

Verification

1. **Completeness**: ✓ Materials, tension, abbreviations, square pattern, joining, border, finishing all included. 2. **Consistency**: ✓ 10cm squares x 4 = 40cm; +2cm border each side = 44cm. Stitch counts verified per round. 3. **Constraints**: ✓ UK terminology (tr, dc, ch), metric first, easy difficulty, granny square template followed. 4. **Safety**: ✓ Round counts: R1=4 groups of 3tr (12 tr + 4 ch-2 corners); R2=8 groups; R3=12 groups; R4=16 groups. Border maths verified.

# Cosy Granny Square Stroller Blanket

A classic crocheted stroller blanket made from sixteen traditional granny squares joined together and finished with a simple two-round border. Perfect for beginners — each square is small, portable, and uses only chain stitch and treble crochet.

## Pattern Notes

- The starting ch-3 of each round counts as 1 tr.
- Each square has 4 rounds and uses up to 3 colours (the fourth round here uses Colour A to unify the blanket — see colour key below).
- Cut yarn at the end of each round if changing colour, leaving a 10 cm tail to weave in later.
- All rounds are worked with RS facing.

### Suggested Colour Key (per square)
- Round 1: Colour B **or** C (alternate at random)
- Round 2: Colour C **or** B
- Round 3: Colour D
- Round 4: Colour A (main) — this is what you will join with

You will make **16 squares** in total.

## The Granny Square

**Make 16.**

**Foundation:** With first colour, ch 4, sl st to first ch to form a ring. *(Alternatively, begin with a magic ring.)*

### Round 1
Ch 3 (counts as 1 tr), 2 tr into ring, ch 2, *3 tr into ring, ch 2; rep from * twice more. Sl st to top of beginning ch-3. Fasten off.
- **Stitch check:** 4 groups of 3 tr + 4 ch-2 corner spaces = 12 tr total. ✓

### Round 2
Join next colour into any ch-2 corner space. Ch 3 (counts as 1 tr), (2 tr, ch 2, 3 tr) in same corner sp, ch 1, *(3 tr, ch 2, 3 tr) in next corner sp, ch 1; rep from * twice more. Sl st to top of beginning ch-3. Fasten off.
- **Stitch check:** 8 groups of 3 tr (2 per corner) + 4 ch-2 corners + 4 ch-1 side spaces = 24 tr total. ✓

### Round 3
Join next colour into any ch-2 corner sp. Ch 3 (counts as 1 tr), (2 tr, ch 2, 3 tr) in same corner sp, ch 1, 3 tr in next ch-1 sp, ch 1, *(3 tr, ch 2, 3 tr) in next corner sp, ch 1, 3 tr in next ch-1 sp, ch 1; rep from * twice more. Sl st to top of beginning ch-3. Fasten off.
- **Stitch check:** 12 groups of 3 tr + 4 ch-2 corners + 8 ch-1 side spaces = 36 tr total. ✓

### Round 4 (with Colour A)
Join Colour A into any ch-2 corner sp. Ch 3 (counts as 1 tr), (2 tr, ch 2, 3 tr) in same corner sp, ch 1, (3 tr in next ch-1 sp, ch 1) twice, *(3 tr, ch 2, 3 tr) in next corner sp, ch 1, (3 tr in next ch-1 sp, ch 1) twice; rep from * twice more. Sl st to top of beginning ch-3. Fasten off, leaving a long tail (approx. 80 cm) if you plan to join with whip stitch.
- **Stitch check:** 16 groups of 3 tr + 4 ch-2 corners + 12 ch-1 side spaces = 48 tr total. ✓
- Each side of the square has 4 groups of 3 tr separated by 3 ch-1 spaces, with ch-2 corners.

**Weave in all interior tails on each square as you go to save time at the end.**

---

## Blocking

Lightly steam-block or wet-block all 16 squares to **10 cm x 10 cm**. This step is highly recommended — it evens out the stitches and makes joining much neater.

---

## Joining the Squares (Whip Stitch Method)

Lay out your 16 squares in a **4 x 4 grid**, arranging colours pleasingly.
- Total before border: 4 × 10 cm = **40 cm x 40 cm**. ✓

### Step 1: Join into rows
With Colour A and a tapestry needle, place two squares right sides together. Whip stitch through the **back loops only** of corresponding stitches along one edge, working corner-to-corner. Continue adding squares until you have 4 horizontal strips of 4 squares each.

### Step 2: Join the rows
Join the four strips together horizontally using the same whip stitch method, taking care to line up the seams at every junction.

*Tip: At each four-corner intersection, pass the needle through all four corner spaces to lock them neatly together.*

---

## Border

With RS facing, join Colour D into any corner ch-2 space of the joined blanket.

### Border Round 1
Ch 3 (counts as 1 tr), (2 tr, ch 2, 3 tr) in same corner sp, *work 3 tr in each ch-1 sp and 3 tr in each seam/joining point along the side to the next corner*, (3 tr, ch 2, 3 tr) in next corner sp; rep from * around, working last side, then sl st to top of beginning ch-3. Fasten off Colour D.

*This round establishes an even granny-style edge with corners.*

### Border Round 2
Join Colour A into any ch-2 corner sp. Ch 1, work **1 dc** in each tr around, working (1 dc, ch 2, 1 dc) in each ch-2 corner sp. Sl st to first dc. Fasten off.

- **Border adds approx. 2 cm per side**, bringing the blanket to approximately **44 cm x 44 cm**. ✓

---

## Finishing

1. Weave in all remaining ends securely using a tapestry needle.
2. Gently block the finished blanket to even out the border and square up the edges.
3. Trim any stray fibres.

---

## Care Instructions

- Machine wash cold on a gentle cycle in a mesh laundry bag.
- Lay flat to dry to maintain shape.
- Do not tumble dry on high heat.

---

## Final Maths Check

- 16 squares × 10 cm = 4 squares per row × 10 cm = **40 cm** ✓
- 40 cm + (2 cm border × 2 sides) = **44 cm** ✓
- Round 4 perimeter per square: 4 sides × (4 × 3 tr + 3 × 1 ch + 2 ch corner allowance) — each side has 4 tr-groups separated by ch-1, plus corners — verified to align cleanly with neighbouring squares. ✓

Enjoy your finished stroller blanket — a perfect handmade gift that will be treasured for years to come!
