Below is a detailed, step-by-step guide for crocheting a “Carnival” Baby Cardigan — a colorful, playful, and beginner-friendly project. Since there is no single standardized “Carnival Cardigan,” this pattern is written in a universal style that you can follow with any DK/light worsted yarn in multiple colors to achieve a carnival-inspired striped effect.
If you want, I can also format this into a printable PDF, add charts, or convert to UK terms.
