This 6 color rainbow crochet pattern is one of my favourite St. Patrick’s Day makes — a beautifully bobbled crochet rainbow that works as a standalone wall hanging OR as the centerpiece of my full St. Patrick’s Day Pot ‘O Gold series. 🌈 Each row of the rainbow uses the bobble stitch to create dimensional, plump arcs of color, and the whole pattern works up faster than it looks.

Whether you’re decorating your kid’s room, putting together a classroom display, or styling for St. Patrick’s Day, this rainbow has so many uses. The bobble stitch gives it that satisfying touchable texture that kids especially love.
