This colorful crochet baby blanket pattern is super sweet and perfect for beginners or intermediate crocheters who want to create something beautiful and textured! The stitch used is a “Spike Stitch” or “Long Double Crochet” technique that adds those stunning vertical lines.
Let me walk you through the step-by-step pattern for this exact design:
🧶 Crochet Baby Blanket Pattern – Vertical Rainbow Stripes
✨ Materials:
- 4–5 colors of worsted weight or baby yarn (soft acrylic or cotton)
- 4 mm or 4.5 mm crochet hook

🔁 Pattern Repeats & Notes
- Multiple of 4 + 2 (for the starting chain)

🧵 Step-by-Step Instructions:
🪄 Foundation Row
- Chain a multiple of 4 + 2 (e.g., ch 34 = 32 + 2)
- Row 1: Sc in 2nd ch from hook, and in each ch across. Turn.
- Row 2: Ch 3 (counts as dc), dc in each stitch across. Turn. (Switch color if following multicolor pattern.)
🌈 Main Pattern Repeat
Let’s say your colors are A (white), B (green), C (yellow), D (pink), E (coral).
Row 3 (Color A – base row):
- Ch 1, sc across. Turn.
Row 4 (Color B – spike row):
- Ch 3, dc in next 3 sts, spike stitch (long dc into stitch 2 rows below)
- Repeat * across the row. Turn.
Row 5 (Color B):
- Ch 1, sc in each st across. Turn.
Row 6 (Color C – next spike row):
- Ch 3, dc in next 3 sts, spike dc into same column as spike 2 rows below
- Repeat * across the row. Turn.
➡️ Continue in this pattern, changing colors every 2 rows:
- Row 7: Sc row
- Row 8: Spike dc row (new color)
- Repeat rows 3–8, alternating colors as shown in the image.
🧷 Ribbed Border (Optional, White Color):
- Once you reach desired length, switch to white yarn.
- Add 3–4 rounds of front post/back post dc for a ribbed border effect.
- Ch 3, alternate fpdc and bpdc around, sl st to join.
💡 Tips:
- Always carry yarn up the side neatly or cut and weave ends if using many colors.
- Make a small swatch to decide how long to make your starting chain.
- Spike stitch should be loose but not floppy – don’t pull too tight.
