Easy Mosaic Overlay Crochet Beanie: Cozy Code Hat
One stitch pattern – so many looks!
Every single hat you see here is made with the exact same crochet stitch pattern – yet each one looks completely different. The secret? The way you combine the colors. The Cozy Code Beanie crochet pattern includes 6 repeatable colorwork charts (all shown in the photos) plus a bonus chart that mixes elements of all six. I honestly couldn’t stop and ended up making 8 hats – the stitches are relaxing, easy to memorize, and a little addictive!
The shape is versatile too: you can work it as a snug-fitting beanie or add length for a stylish slouchy hat.
Why you’ll love this crochet beanie pattern:
- Meditative, rhythmic stitches that make crocheting feel like pure calm.
- A gentle introduction to mosaic overlay crochet in a small, rewarding project.
- Mix & match designs – use the provided color charts or create your own stripe sequence.
- Perfect for family sets – sizes from baby to large adult.
- Stash-friendly – combine leftover yarns of the same weight in endless ways.
- Adaptable design – easy to adjust for size, fit, or yarn type.
- Ideal for charity makes – quick, warm, and unique hats.
- Great for sellers – one pattern gives you endless variety just by changing colors.
