Crochet Blanket Stitch: Shell Diamond Pattern Guide
Overview
The shell diamond blanket stitch is a textured crochet pattern made using repeating fan (shell) stitches. By alternating colors every row or two, you create a striking geometric diamond effect—perfect for blankets, scarves, or baby wraps.
Pattern Structure
This stitch is worked in rows, with shells stacked between gaps to form a diamond pattern.
Each “shell” is typically:
5 double crochets (5 dc) into the same stitch or space
Step-by-Step Instructions
1. Foundation Chain
Chain a multiple of 6 + 2
2. Row 1 (Base Row)
Work 1 dc in the 4th chain from hook
Skip 2 chains
Work 5 dc in next chain (this forms your first shell)
Skip 2 chains
Work 1 sc in next chain
Repeat across
End with a dc
3. Row 2 (Start Diamonds)
Chain 3 and turn
Work 5 dc into the center (sc) of previous row
Skip to next shell
Work 1 sc into the center of that shell
Repeat across
💡 This creates the offset that forms the diamond shape.
4. Row 3 and Beyond
Repeat Row 2
Change colors every row or every two rows for the striped diamond effect
