Rainbow Baby Blanket Crochet Pattern

A rainbow baby blanket is a beautiful and vibrant project, perfect for bringing warmth and charm to any nursery. This simple yet visually striking pattern features a lovely ribbed texture, achieved by working in the back loops only (BLO). The design is easily adjustable, allowing you to customise the size to suit your needs. Whether you’re creating a heartfelt gift or making something special for your little one, this blanket is sure to spread joy!

Why You’ll Love This Project

Crocheting a baby blanket is one of the most rewarding handmade projects. The combination of soft, cosy yarn and a stunning array of rainbow colours makes this blanket a standout piece, whether for personal use or as a thoughtful present.

This pattern is designed with simplicity in mind, making it ideal for beginners while still being enjoyable for more experienced crocheters. By following a repeating colour sequence and using basic half double crochet (hdc) stitches, you’ll create a beautiful striped effect that looks impressive yet is easy to master.

Beyond its visual appeal, the ribbed texture adds an extra touch of comfort. The stretchiness and plush feel, created by working into the back loops, make this blanket especially soft and snuggly.

The flexibility to adjust the size means you can make it exactly as you like—whether a small stroller blanket or a larger throw for extra cosiness. No matter how you choose to use it, this Rainbow Baby Blanket will bring warmth, comfort, and a cheerful splash of colour to any setting.

Customisation Options

Adjust the width by increasing or decreasing the number of starting chains.
Make it longer by adding more rows while maintaining the colour sequence.
The ribbed texture is achieved by working in the back loops only (BLO) of each stitch across every row.
