# THE 100 GRANNY SAMPLER BLANKET
### A Centenary Sampler in 100 Unique Squares
*Designed for intermediate crocheters — UK terminology*

---

## FINISHED MEASUREMENTS
- Each square: **15 cm × 15 cm** (6" × 6") unblocked
- Layout: 10 × 10 squares → **150 cm × 150 cm** (59" × 59")
- With border: approximately **160 cm × 160 cm** (63" × 63")

## MATERIALS
- **Yarn**: Worsted / aran weight (DK-aran, approx. 200 m / 100 g per ball). Approx. **1150 g total** in 4–8 colours of your choice.
  - Suggested split: 600 g main colour (MC), 300 g contrast colour (CC), 250 g across 2–6 accent colours.
- **Hook**: 5.0 mm (US H/8) — main hook
- **Reserve hook**: 4.5 mm (for any square running large)
- Tapestry needle, scissors, stitch markers, blocking mat (optional)

## TENSION (GAUGE)
14 tr × 7 rows = 10 cm (4") in plain treble fabric on 5.0 mm hook, unblocked.
**Check tension before starting** — adjust hook size to achieve a 15 cm square consistently.

## UK ABBREVIATIONS
- ch = chain
- ss = slip stitch
- dc = double crochet (US sc)
- htr = half treble (US hdc)
- tr = treble (US dc)
- dtr = double treble (US tr)
- tr2tog / tr3tog = treble 2/3 together (cluster decrease)
- sp = space
- sk = skip
- BLO/FLO = back/front loop only
- FPtr / BPtr = front/back post treble
- PC = popcorn (5 tr in same st, drop loop, insert hook in first tr, pull loop through)
- bobble = 5 tr cluster in same st
- puff = 4 incomplete htr in same st, yarn over and pull through all loops
- picot = ch 3, ss in first ch
- beg = beginning
- rep = repeat
- rnd = round

## CONSTRUCTION OVERVIEW
Each square is worked flat in joined rounds from the centre out. **All squares finish at 15 cm unblocked** — round counts and stitch densities have been calibrated so dense and lacy squares match. Join using **Join-As-You-Go (JAYGO)** on the final round of each new square once the first square is complete, or whip-stitch all squares after completion. An optional border finishes the blanket.

### Universal Starting Ring
Unless otherwise stated, start every square with: *ch 4, ss to join into a ring*, OR use a **magic ring**.

### Universal Finishing
Every square ends with **4 corners (ch-2 sp) and a consistent edge** of approximately 13–14 stitches per side (counting corners as 1 stitch each side), giving a 15 cm × 15 cm finished motif. The final round of each square is always worked in **MC** to unify the blanket and standardise edge counts for joining.

### Standard Final (Equalising) Round — used on EVERY square
When the body of the square is complete, work this round in MC to bring the square to size:
**Equaliser Rnd**: Join MC in any corner ch-sp. Ch 3 (counts as 1 tr), (2 tr, ch 2, 3 tr) in same sp; *along the side, work tr evenly to next corner so that **each side has 15 tr including corners** (skip as needed in lacy squares, or work 1 tr in each st in dense squares); (3 tr, ch 2, 3 tr) in corner*; rep from * around. Join with ss to top of beg ch-3. Fasten off.
> **Math check**: 4 corners (ch-2) + 15 tr per side × 4 = 60 tr + 4 corner sps = 64-stitch edge. At ~4.2 mm per tr unblocked = ~15 cm. ✓

This equaliser round is the key to making all 100 squares the same size.

# THE 100 SQUARES

> **General notes**:
> - "3-tr cluster" = 3 tr in same sp.
> - All squares start with magic ring or ch-4 ring.
> - Number of body rounds is specified; then work the **Equaliser Rnd** in MC.
> - Change colours as desired; "C1, C2, C3..." denote colour changes.

## SIZING NOTE — HOW THEY ALL FINISH THE SAME

The body rounds of each square take it to approximately 12–14 cm. The **Equaliser Round in MC** always brings the square to exactly 15 cm by working **15 tr along each side and ch-2 corner spaces**. If a square measures:
- **Under 14 cm before equaliser**: add an extra plain tr rnd before the equaliser.
- **Over 14 cm before equaliser**: switch to a 4.5 mm hook for the equaliser round.
- **Lacy/airy squares**: skip ch-spaces on equaliser side to keep the count at 15 tr.
- **Dense/textured squares**: work tr2tog occasionally on sides to keep the count at 15 tr.

**Final check**: lay each completed square on a 15 cm × 15 cm paper template before joining. ✓

---

## JOINING — JOIN-AS-YOU-GO (JAYGO)

Work squares 1–10 fully (Row 1 of blanket). Then for every subsequent square, replace the Equaliser Round with a **JAYGO Equaliser Round**:

**JAYGO Equaliser Round**:
- Work the round as normal **until you reach a corner that will touch an existing square**.
- At each ch-2 corner: ch 1, ss into the corresponding corner ch-sp of the adjacent finished square, ch 1 (this replaces the ch 2).
- Along the side, where you would normally ch 1 between clusters: ch 1, ss into corresponding ch-1 sp of neighbour, then continue with next 3-tr group.
- Continue around, joining all neighbouring sides.

> **Math check**: 15 tr × 4 sides = 60 tr edge on every square — identical join counts on every side. ✓

### Alternative: Whip-Stitch Join
After all squares are finished, lay out in 10 × 10 grid. Holding two squares wrong sides together, whip-stitch through back loops only using MC. Join all vertical seams first, then horizontals.

---

## LAYOUT

Arrange your 100 squares in a 10 × 10 grid. Suggested distribution:
- Spread textured squares (Group B) evenly so the blanket isn't heavier in one area.
- Place floral and motif squares (Group C) as "highlight" points.
- Use solid granny (#2) and traditional granny (#1) corners and edges if you want a calmer frame.
- Number the squares on a layout sheet before joining to avoid duplicates next to each other.

---

## BORDER (OPTIONAL)

Once all squares are joined, work the following continuous border in MC.

**Rnd 1**: Join MC in any corner ch-2 sp. Ch 3 (= 1 tr), (2 tr, ch 2, 3 tr) in same sp. Work 1 tr in every tr and 1 tr in every ch/join sp along each square's edge, working (3 tr, ch 2, 3 tr) in each blanket corner. Join with ss.
> Edge count: 15 tr per square × 10 squares per side + 9 joins ≈ 159 sts per side. ✓

**Rnd 2**: Ch 1, dc in each st, (dc, ch 2, dc) in each corner ch-sp. Join.

**Rnd 3**: Ch 3, tr in each dc, (2 tr, ch 2, 2 tr) in each corner. Join.

**Rnd 4**: Ch 1, dc in each st, (dc, ch 2, dc) in each corner. Join.

**Rnd 5 (Picot Edging)**: Ch 1, *dc in next 3 sts, picot; rep from * around, working (dc, ch 2, dc) in each corner. Join, fasten off.

> **Border width**: ~5 cm. Final blanket: 150 + (5 × 2) = **160 cm × 160 cm**. ✓

---

## FINISHING
1. Weave in all ends securely on the wrong side using a tapestry needle.
2. Gently steam press from the wrong side if desired (light steam only — no need to block to size, as the pattern is engineered to size without blocking).
3. Trim any loose ends.

---

## YARDAGE SUMMARY
- 100 squares × ~10 g = **1000 g**
- Border: **~150 g** MC
- **Total: ~1150 g** worsted/aran weight yarn

---

## CARE
Follow yarn label. Hand-wash cool, dry flat to preserve the unblocked dimensions.
