Koosh Retro Crochet Beanie (Free Beginner Retro Granny Stripe Beanie Pattern)
This pattern creates a beanie using the classic granny stripe stitch, a variation of the traditional granny square motif. It’s worked in rounds, starting from the crown and expanding outwards, with a color change in each round to create a striped effect. The pattern concludes with a ribbed band worked in rows and attached to the main body.

- Chain (ch)

- Working in spaces between stitches
- Changing colors
- Working in the back loop only (for the band)
- Basic seaming

Construction:
- Crown: The hat begins with a small ring of treble crochets (UK terminology – equivalent to US double crochets).
- Granny Stripe Rounds: The body of the hat is worked in rounds using the granny stripe stitch. This involves working clusters of 3 treble crochets (UK tr / US dc) into the spaces between the clusters of the previous round. Each round increases the number of clusters. The rounds alternate colour.
- Color Sequence: The pattern establishes a specific color sequence (Col1, Col2, Col3, Col4) that is repeated throughout the body of the hat.
- Band:
- The band is worked separately in rows using a smaller hook.
- It uses a technique that combines single crochet (UK dc / US sc) and a modified stitch to attach the band to the body of the hat as you go.
- The band is worked in the back loop only to create a ribbed texture.
- The ends of the band are seamed together.
