Pattern Notes

  • Use an H-8 5 mm crochet hook for the hat.
  • Use a G-6 4 mm crochet hook for the brim.
  • The bobble stitches will pop out on the wrong side. Push them through to the right side as you go.
  • The brim is made separately and sewn to the hat.
  • The chain at the beginning of each round does not count as your first stitch. 
  • Join each round with a slip stitch to the first stitch made in that round. 
  • Repeat instructions between the asterisks (*) for the rest of the round.
  • You are crocheting in the round from the top of the hat down.
  • The pattern is written in US terms.

Special Stitches

Bobble Stitch (bo):

  1. Yarn over and insert hook in next stitch
  2. Yarn over and pull up a loop
  3. Yarn over and pull through 2 loops
  4. Repeat steps 2 & 3 four times in the same stitch. You will have 6 loops on your hook.
  5. Yarn over and pull through all 6 loops

Magic Circle Alternative

If you’re not comfortable with using a magic circle, you can use an alternative method to make round 1 of the beanie. This method is just as effective and might be easier for beginners.

Round 1: Chain 4, make 12 dc in the 4th ch from the hook, join (12 stitches)

Adding the brim

Brim is made separately and then sewn onto the hat. I used a G-6 4 mm crochet hook size.

Row 1: Ch 7, sc in 2nd ch from hook and each rem ch, turn (6 stitches)

Row 2: Ch 1, sc in each st in the back loops only, turn (6 stitches)

Child Size: Repeat row 2 for a total of 72 rows.

Adult Size: Repeat row 2 for a total of 84 rows.

Use your tapestry needle to sew the brim to the hat. Sew each stitch from the hat to a row of the brim. The brim will stretch as you go.

Adding a pom pom

  1. Wind the yarn around both arches. 
  2. Cut the yarn along the middle gap.
  3. Tie with a piece of scrap yarn. 
  4. Open the arches and remove the pom pom.
  5. Trim any loose ends.

Attach the pom pom to the top of your hat.

Finishing

Weave in your ends.
