Prism Cardigan Crochet Pattern

The Prism Cardigan is a joyful, colour-loving crochet design that celebrates texture, creativity and slow making. With its beautiful bobble triangle feature on the back and classic cardigan shape, this is a piece that feels both playful and timeless.

The standout detail is the prism-inspired triangle worked in bobble stitches, which creates a stunning focal point and makes this cardigan truly special. You can use up leftover yarn, experiment with colour combinations, or keep things simple in a single shade. The pattern includes clear guidance on colour changes and layout, so you can make this design completely your own.

The cardigan is worked from the top down with a raglan yoke, allowing you to create a lovely fit as you go. Once you settle into the rhythm of the bobble rows, this becomes a wonderfully relaxing and satisfying project.

Clear stitch counts, detailed instructions, helpful photos and step by step guidance are included throughout the pattern to support you every step of the way.

This is a wonderful project for confident beginners and intermediate crocheters who enjoy colour work, texture and making garments that truly stand out.

Have the loveliest time crocheting the Prism Cardigan.
