OCTOPUS HAT - no sew! (almost)

Free Crochet Octopus Hat Pattern

Bring a splash of creativity to your crochet with this fun and whimsical Octopus Hat! Designed with a comfortable beanie base and eight playful, curling tentacles, this project is perfect for costume parties, themed events, or simply adding a bit of personality to your cold-weather gear.


At first glance, the pattern might seem it involves a lot of counting—but thanks to strategic stitch marker placement, the tentacle shaping is easy to manage and surprisingly relaxing once you get going. Best of all, the tentacles are worked directly onto the hat—no sewing required—which makes for a seamless, sturdy finish and saves time in the final assembly. The only part that needs to be sewn on is the eyes.


Using basic stitches and simple shaping, this pattern is suitable for confident beginners and experienced crocheters alike. If you're comfortable with single crochet, increases, slip stitches, and chains, you're ready to jump in!

Place a stitch marker in the last stitch.


Do not fasten off. Continue to Tentacles.


Notes about the Tentacles:


  • Each tentacle takes up 7 stitches on the hat. Leave 3 stitches between tentacle bases. Total repeat area per tentacle = 10 stitches.


  • SLST into the bottom edge of the hat does not count as a stitch. Be sure to skip the SLST at the beginning of each row.


  • Move the stitch markers up a row as you work down the tentacle. When you're done with a tentacle, remove the stitch markers so the can be used in the next tentacle.
