Materials

• Crochet Hook: 5 mm (USA H-8)

When choosing colors, think about the mood and personality you want your mermaid blanket to express. Ocean lovers often enjoy deep sea palettes such as navy, midnight teal, emerald, and lagoon green. For a softer and more magical look, pastel blends like lavender, blush pink, seafoam, and baby blue create a dreamy, fairytale aesthetic.

Gradient and ombré yarns work beautifully especially those that transition from blues to purples or greens to turquoise, giving the tail a natural shimmering effect. If you’re making it for kids, consider playful rainbow twists, glitter-infused yarns, or colorways inspired by animated mermaids.

As for fibers, choose yarns that are soft, warm, and durable. Anti-pill acrylic is a great choice because it’s comfortable, washable, and keeps its shape. Bamboo and bamboo-blend yarns offer silky drape and a soft sheen that enhances the scale texture.

Wool blends add warmth and structure, making them ideal for colder climates. Self-striping yarns can eliminate the need for color changes, while sparkle yarns give your tail a magical glimmer  perfect for an enchanted under-the-sea look.
