This is a 2-color crochet square motif (granny-style blocks arranged to form a diamond pattern when joined). I’ll explain step by step how to make ONE square, then how the big pattern is formed.
🧶 MATERIALS
- Yarn: medium weight (4)
- Colors: A = Purple, B = White
- Hook: 4.5 mm or 5 mm
- Yarn needle, scissors
📏 SQUARE SIZE
Approx. 12 × 12 cm (5 × 5 inches)
🔷 STITCHES USED
- ch = chain
- sc = single crochet
- dc = double crochet
- sp = space
- sl st = slip stitch
🔹 HOW TO MAKE ONE SQUARE (IMPORTANT PART)
⚠️ This square is worked in rows, not rounds.
🟣 ROW 1 (Color A – Purple)
- Ch 19
- Dc in 5th ch from hook (first cluster made)
- Dc 2 more times in same chain (3 dc total)
- Skip 2 ch
- 3 dc in next ch
- Repeat across
➡️ You should have 6 granny clusters
Turn work
⚪ ROW 2 (Color B – White)
- Attach white yarn
- Ch 3 (counts as dc)
- Dc 2 in first sp (between clusters)
- Ch 2
- 3 dc in next sp
- Repeat across
- Last cluster: 3 dc in top of turning ch
Turn
🟣 ROW 3 (Purple)
- Ch 3
- Dc 2 in first sp
- Ch 2
- 3 dc in next sp
- Repeat across
Turn
⚪ ROW 4 (White)
Same as Row 2
Turn
🟣 ROW 5 (Purple)
Same as Row 3
Turn
⚪ ROW 6 (White – final row)
Same as Row 2
Fasten off
You now have 1 complete square
🔹 HOW MANY SQUARES?
For small blanket:
- 6 × 6 squares = 36 squares
For big blanket:
- 8 × 10 squares = 80 squares
🔹 JOINING (VERY IMPORTANT FOR DIAMOND EFFECT)
Step 1: Rotate Squares
- Turn every square 45° (diamond position)
Step 2: Layout Pattern
Arrange like this:
⬜🟪⬜🟪⬜
🟪⬜🟪⬜🟪
⬜🟪⬜🟪⬜
Step 3: Join Method (Best look)
Use single crochet join
- Hold two squares wrong sides together
- Insert hook through both loops
- Sc across
- Match colors to keep lines clean
🔹 BORDER (TO MATCH PHOTO)
- Join white yarn in any corner
- Sc evenly around
- 3 sc in each corner
- Sl st to close
- Optional: crab stitch border
🌸 WHY THE PATTERN WORKS
- Alternating colors create illusion
- Diamond shapes appear when rotated
- Joining stitches form lattice lines
💡 PRO TIPS
✔ Block squares before joining
✔ Count clusters every row (must be same)
✔ Keep ch-2 spaces loose
✔ Use same hook for all squares
