Great! Here’s a detailed step-by-step written pattern to make the Four Triangle Granny Square like the one in this photo:

๐ธ Four Triangle Granny Square โ Full Pattern
Each triangle is worked in rows (not rounds), and then 4 triangles are joined to form the square.
๐งถ Materials:
- Yarn (4 colors: pink, blue, white, grey)
- Crochet hook (size suitable for yarn, e.g., 4mm)
- Scissors
- Yarn needle
๐บ Step 1: Make 1 Granny Triangle
Repeat this step for each of the 4 colors.
Row 1:
- Start with magic ring, or ch 4, sl st to form ring.
- Ch 3 (counts as first dc), 2 dc in ring, ch 3 (corner), 3 dc in ring.
- You now have 2 granny clusters and a ch-3 corner.
- Turn.

[Total: 2 clusters, 1 ch-3 space]
Row 2:
- Ch 3 (counts as dc), 2 dc in first space.
- In ch-3 corner space: 3 dc, ch 3, 3 dc.
- 3 dc in space between clusters.
- Turn.
[Total: 4 clusters]
Row 3:
- Ch 3, 2 dc in first space.
- In next space: 3 dc.
- In corner: 3 dc, ch 3, 3 dc.
- In next space: 3 dc.
- 3 dc in last space.
- Fasten off.

[Total: 6 clusters]
โ Repeat this triangle pattern using each of your 4 colors.
๐งฉ Step 2: Join the 4 Triangles
You can sew or crochet them together in a square layout:
Layout:
[ Triangle 1 ] [ Triangle 2 ]
[ Triangle 3 ] [ Triangle 4 ]
- Align the flat edges of each triangle together.
- Use a yarn needle and whipstitch them, or use slip stitch join with hook.
Tip: Join triangles at the corner chains to keep the center neat.
๐ฒ Step 3: Add a Border Round (Optional but Recommended)
Use any of the colors (e.g., blue) to give a clean border:
- Join yarn in any corner.
- Ch 3 (counts as dc), 2 dc in same corner space, ch 2, 3 dc in same corner (corner made).
- 3 dc in each space between clusters along sides.
- In each corner: 3 dc, ch 2, 3 dc.
- Sl st to top of starting ch-3 to join.
- Fasten off and weave in ends.

๐งผ Finishing Touch:
- Block the square if needed to make it perfectly flat.
- Weave in all yarn tails neatly on the back side.
