Planning

1. **Design Strategy**: The user wants a 1-inch granny square pattern at beginner difficulty. This is a very small square, so the design must be minimal — likely just Round 1 of a traditional granny square (a centre cluster ring with corner chains). The template is "Granny Square Blanket," so I need to include: materials, tension, the square pattern itself, a joining method, and an optional border. I'll use UK terminology throughout (dc = double crochet [US sc], tr = treble crochet [US dc], ch = chain, sl st = slip stitch). Metric measurements first, inches in parentheses. The target finished size per square is approximately 2.5 cm (1 inch). 2. **Construction Plan**: - A 1-inch / 2.5 cm granny square in worsted weight yarn is extremely compact. With worsted weight (approximately 4–5 mm hook), a traditional granny square Round 1 only (magic ring, [3 tr, ch 2] x4, close) typically measures about 4–5 cm. To achieve a true 1-inch (2.5 cm) square in worsted weight, we need to use a smaller hook than standard and keep the square to just the first round, OR accept that in worsted weight a single-round granny square will be approximately 1 inch (2.5 cm) if worked very tightly or with a 3.5 mm hook. Let me reconsider: A standard worsted weight granny square Round 1 with a 5 mm hook is typically about 4–5 cm. With a 3.5 mm hook (still within the worsted range, on the tighter end), it could be closer to 3–3.5 cm. A true 1-inch granny in worsted weight is technically very challenging — it would be more achievable with fingering/lace weight. However, the user specified worsted weight and 1 inch. I should: - Flag this tension consideration honestly in the pattern - Recommend a 3.5 mm hook for a tighter fabric - Note that the finished square will be approximately 2.5–3 cm (1–1¼ inches) — being transparent about the slight variation - Keep the square to Round 1 only (the simplest granny structure) Actually, re-examining: the user said "1 inch granny square" and the template is "Granny Square Blanket." This could mean they want a blanket made of 1-inch granny squares. Let me design accordingly — a complete blanket pattern where each square is ~1 inch (2.5 cm), joined together to make a blanket. I'll use a 3.5 mm hook with worsted weight and note tension carefully. A single round granny square in worsted weight at tight tension can come close to 2.5 cm. For the blanket, I'll specify a sample size (e.g., baby blanket, lap blanket) and note that the crafter can make as many squares as needed. 3. **Quality Assurance**: - A 1-inch granny square in worsted weight at standard gauge (5 mm hook) is not achievable without extremely tight tension. I must be honest: with a 3.5 mm hook and worsted weight, we can get approximately 2.5 cm (1 inch) per square. I'll recommend this and call it out. - The pattern must be Round 1 only for a 1-inch result. Two rounds would exceed 1 inch in worsted. - Joining method: whip stitch is best for flat joins and beginner-friendly. At this tiny size, join-as-you-go is complex, so whip stitch preferred. - Border: optional simple round of dc/tr around the entire assembled blanket. - I need to provide a sample blanket size and the number of squares required. - Stitch count per round must be verified: Magic ring, 3tr into ring [ch2, 3tr] 3 times, ch2, sl st to top of first tr. = 12 tr + 4 ch-2 corner spaces. Each side has 3 tr. This is standard and correct. 4. **Final Calculations**: - Hook: 3.5 mm (to achieve ~2.5 cm / 1 inch square with worsted weight) - Yarn: Worsted weight (approx. 100m / 109 yds per 50g) - Tension: 1 granny square = approximately 2.5 cm × 2.5 cm (1 inch × 1 inch) using 3.5 mm hook - Sample blanket size: Baby blanket approximately 30 cm × 40 cm (12 × 16 inches) - Squares needed: 12 × 16 = 192 squares across a grid... wait, let me reconsider. - If each square = 2.5 cm, then for a 30 cm wide blanket: 30 ÷ 2.5 = 12 squares per row - For 40 cm length: 40 ÷ 2.5 = 16 squares per column - Total: 12 × 16 = 192 squares - That's a LOT of tiny squares. This is accurate but I should note multiple size options. Let me offer size options: - Small sample/coaster: 5 × 5 squares = 25 squares, ~12.5 cm × 12.5 cm (5 × 5 inches) - Baby blanket: 30 × 40 cm = 12 × 16 = 192 squares - Lap blanket: 50 × 60 cm = 20 × 24 = 480 squares - I'll present the baby blanket as the main example with a note on scalability. Yarn quantities: - Each 1-inch square uses approximately: Magic ring + 12 tr + 8 ch = roughly 60–70 cm (about 24–28 inches) of yarn per square - I'll estimate ~70 cm (0.7m) per square - 192 squares × 0.7m = ~134m per colour, total ~134m for single colour - With joining and border: add ~20% = ~160m / 175 yds - Round up to ~200m / 220 yds for safety - For a multi-colour version, divide by number of colours Stitch verification for Round 1: - Start: Magic ring - Ch 3 (counts as first tr) — this is 1 tr - 2 tr into ring = total 3 tr in first corner cluster - *Ch 2 (corner space), 3 tr into ring* — repeat 3 more times = 3 more corner ch-2 spaces + 9 more tr - Total: 4 corner clusters × 3 tr = 12 tr stitches ✓ - Total: 4 corner ch-2 spaces ✓ - Close with ch 2, sl st to top of ch-3 (or 3rd ch of starting ch-3) — this closes the 4th corner - Wait, let me re-check the standard Round 1 instruction: - Magic ring - Ch 3 (counts as tr), 2 tr into ring, ch 2 [corner made] - (3 tr into ring, ch 2) × 3 times - Sl st to top of ch-3 to join - = 4 groups of 3 tr = 12 tr; 4 ch-2 corner spaces ✓ - This is correct and standard.

# Tiny Granny Square Blanket
### 1-Inch (2.5 cm) Granny Squares in Worsted Weight

---

## About This Pattern

This pattern creates miniature granny squares, each measuring approximately 2.5 cm × 2.5 cm (1 inch × 1 inch), which are then joined together to form a blanket. Each square is worked in a single round, making this a wonderful project for using up yarn scraps and for practising the foundational granny square technique.

**⚠️ Important Note on Tension:** A 1-inch granny square in worsted weight yarn requires a smaller hook than the standard recommendation for this yarn weight. Please read the Tension section carefully and swatch before beginning your blanket.

---

## Difficulty Level
**Beginner**

---

## Materials

- **Yarn:** Worsted weight yarn (approx. 200 ply / aran weight, CYCA #4), such as a smooth wool or wool-blend for ease of stitching
  - *Yarn quantity: see Size Chart below*
  - *Suggested colours: as many or as few as desired — this pattern is perfect for scraps*
- **Hook:** 3.5 mm crochet hook *(Note: a smaller hook than standard for worsted weight is used intentionally to achieve the 1-inch tension — see Tension section)*
- **Blunt-ended tapestry needle** (for weaving in ends and whip-stitch joining)
- **Scissors**
- **Stitch markers** (optional, helpful for counting squares during layout)
- **Blocking mats and pins** (optional but recommended for a neat finish)

## Tension (Gauge)

> **1 completed granny square = 2.5 cm × 2.5 cm (1 inch × 1 inch)**
> Worked in treble crochet using a 3.5 mm hook and worsted weight yarn.

**How to check your tension:** Work 3–5 sample squares. Lay them flat without stretching and measure across the widest point of each square (corner to corner along a straight side, not diagonally). Each square should measure 2.5 cm (1 inch). If your squares are larger than 2.5 cm, try a 3.0 mm hook. If your squares are smaller, try a 4.0 mm hook.

*Taking time to check your tension before beginning your blanket will save considerable time and yarn.*

## Sizes

The blanket is formed by joining individual squares in a grid. Choose your desired finished size from the chart below, or calculate your own using the formula:
> **Number of squares = (Width in cm ÷ 2.5) × (Length in cm ÷ 2.5)**

| Size | Finished Dimensions | Grid | Total Squares | Yarn Required (single colour) |
|---|---|---|---|---|
| Swatch / Coaster | 12.5 cm × 12.5 cm (5 × 5 in) | 5 × 5 | 25 squares | ~20 m / 22 yds |
| Pram / Doll Blanket | 25 cm × 30 cm (10 × 12 in) | 10 × 12 | 120 squares | ~90 m / 99 yds |
| Baby Blanket | 30 cm × 40 cm (12 × 16 in) | 12 × 16 | 192 squares | ~145 m / 158 yds |
| Lap Blanket | 50 cm × 60 cm (20 × 24 in) | 20 × 24 | 480 squares | ~360 m / 394 yds |

**Yarn quantities include approx. 15% extra for joining and an optional border. For multi-colour versions, divide the total yardage by the number of colours used (assuming equal distribution).**

*The Baby Blanket (12 × 16 grid, 192 squares) is used as the sample size throughout these instructions.*

## Pattern Instructions

### THE GRANNY SQUARE
*(Make as many as required — see Size Chart)*

**Finished size:** 2.5 cm × 2.5 cm (1 inch × 1 inch)
**Stitch count at end of Round 1:** 12 tr, 4 ch-2 corner spaces

---

**Foundation:** Make a magic ring (or ch 4, sl st to first ch to form a ring).

**Round 1:**

1. Ch 3 *(this counts as your first tr throughout)*.
2. Work 2 tr into the ring. *(First 3-tr corner cluster made. Total so far: 3 tr.)*
3. Ch 2. *(First corner space made.)*
4. \*Work 3 tr into the ring. Ch 2.\* *(Second corner cluster and space made.)*
5. Rep from \* to \* twice more. *(Third and fourth corner clusters and spaces made. Total: 12 tr, 4 ch-2 spaces.)*
6. Sl st to the top of the beg ch-3 to join the round. *(Round 1 complete.)*
7. Pull yarn tail gently to close the magic ring.
8. Fasten off, leaving a tail of approx. 15 cm (6 inches) for weaving in.

> **Stitch count check:** You should have **4 corner ch-2 spaces** and **4 clusters of 3 tr** (= 12 tr total) evenly spaced around your square. Each side of the square has exactly 3 tr across it. ✓

---

**Finishing each square:**
- Weave in the yarn tail from the magic ring on the wrong side.
- Leave the fastening-off tail to use for joining, or weave it in and use a separate length of yarn for joining — whichever you prefer.
- Block your squares lightly if desired: spritz with water, pin to blocking mats in a square shape (2.5 cm × 2.5 cm / 1 inch × 1 inch), and allow to dry fully.

---

### JOINING THE SQUARES

**Method: Whip Stitch Join (Recommended for Beginners)**

Whip stitch creates a visible ridge on the right side of the blanket if worked with the wrong sides together, or a hidden seam on the wrong side if worked with the right sides together. Both are correct — choose your preference.

**You will need:** Blunt tapestry needle, approx. 60 cm (24 inches) of yarn per seam.

**To join two squares:**

1. Lay two squares side by side with the wrong sides facing each other *(this gives a decorative ridge on the right side, traditional in granny square work)*.
2. Thread your tapestry needle with matching or contrasting yarn.
3. Align the edges to be joined so that the corner ch-2 spaces meet at each end.
4. Insert the needle from front to back through the outermost loops of the corner ch-2 sp on both squares simultaneously. Pull yarn through, leaving a 5–8 cm (2–3 inch) tail.
5. \*Insert the needle from front to back through the next corresponding loops (or ch spaces) on both squares. Pull yarn through snugly but not so tight as to distort the squares.\*
6. Rep from \* to \* along the full length of the edge until you reach the opposite corner ch-2 sp.
7. Work one final stitch through the corner ch-2 sp on both squares.
8. Fasten off securely and weave in the ends.

> **Tip:** Work at a consistent tension throughout each seam. The whip stitch should be firm but should not pull the squares out of shape.

---

**Assembly Layout:**

For the Baby Blanket (12 × 16 grid):

1. Arrange all 192 squares on a flat surface in 16 rows of 12 squares each.
2. If using multiple colours, arrange them in your preferred pattern (random, striped, gradient, etc.) before beginning to join. Take a photograph of your layout to refer back to.
3. **Join squares into rows first:** Join the squares in Row 1 together (12 squares into a strip = 11 seams). Repeat for all 16 rows.
4. **Join the rows together:** Lay Row 1 and Row 2 side by side and join along their long edges. Continue joining rows together until all 16 rows are connected (= 15 row seams).

> **Inline check:** 12 squares per row × 16 rows = 192 squares total. 11 seams per row × 16 rows = 176 vertical seams. 15 seams joining 16 rows = 15 horizontal seams. Total seams: 176 + 15 = 191 seams. ✓ *(One fewer seam than the number of squares — this is always correct for a flat grid.)*

---

### OPTIONAL BORDER

A simple border unifies the blanket and gives it a neat, finished edge.

**Materials:** Approx. 15–20 m (16–22 yds) of yarn in your chosen border colour.

**Instructions:**

Join yarn with a sl st to any corner ch-2 sp of the assembled blanket.

**Round 1 (Right Side):**
Ch 3 *(counts as tr)*, work 2 tr into the same corner sp, ch 2, work 3 tr into the same corner sp. *(First corner complete.)*

\*Work 3 tr into each ch-2 sp along the edge, working [3 tr, ch 2, 3 tr] into each corner ch-2 sp when you reach it.\*

Rep from \* to \* around all four sides of the blanket.

Sl st to top of beg ch-3 to join. Fasten off and weave in all ends.

> **Optional Round 2:** For a wider border, work a second identical round, joining with a sl st to the corner ch-2 sp and repeating the pattern above.

---

## Finishing

1. Weave in all remaining yarn ends securely on the wrong side of the blanket.
2. Block the completed blanket: soak gently in cool water, squeeze out excess moisture carefully (do not wring), lay flat on blocking mats, and pin to the correct dimensions. Allow to dry completely — this may take 24–48 hours.

**Finished dimensions (Baby Blanket):** approx. 30 cm × 40 cm (12 × 16 inches). *(Note: seam allowance and blocking may adjust the final measurement by ±1–2 cm.)*

---

## Tips for Success

- **Work to tension:** At this small scale, every millimetre matters. Swatch carefully.
- **Keep joins consistent:** Use the same yarn tension and direction for every whip stitch seam to ensure the blanket lies flat.
- **Organisation:** Use small resealable bags or paper clips to keep joined rows together as you work.
- **Colour planning:** Lay out all your squares before joining a single seam. It is much easier to rearrange squares before they are joined.
- **Magic ring vs. foundation chain:** The magic ring closes more neatly at the centre of a tiny square. If you find it difficult, a ch-4 ring works well too — the small gap in the centre is less visible at this scale than in larger squares.

---

## Pattern Notes

- This pattern uses **UK crochet terminology** throughout. If you are accustomed to US terminology, please note that **tr (treble crochet)** in this pattern = **dc (double crochet)** in US terms.
- All measurements are given in **centimetres first**, with inches in parentheses.
- **Tension** is the UK/Australian term for what is called "gauge" in US patterns.
- This pattern is written for a **Baby Blanket** sample size. Instructions are identical for all sizes — simply make the required number of squares as listed in the Size Chart.
