Sure, here’s a simple and free pattern for a men’s half double crochet beanie:

Materials Needed:

  • Worsted weight yarn in the color of your choice
  • Crochet hook size H/8 (5.0mm)
  • Yarn needle
  • Scissors

Abbreviations:

  • HDC: Half Double Crochet
  • CH: Chain
  • SL ST: Slip Stitch
  • ST: Stitch

Instructions:

Step 1: Start with a Magic Ring

  1. Create a magic ring by making a loop with the yarn, leaving a tail of about 4 inches. Insert your hook into the ring, yarn over, pull up a loop, and chain 1 (this does not count as a stitch). This is your starting point.

Step 2: Begin the First Round

  1. Work 10 HDC stitches into the magic ring. To make a HDC: yarn over, insert your hook into the ring, yarn over again, pull up a loop (you should have 3 loops on your hook), and then yarn over and pull through all 3 loops. This completes one HDC. Continue this until you have 10 HDC stitches in the magic ring.

Step 3: Close the Ring

  1. Pull the tail of the magic ring to close the circle. Slip stitch into the first HDC to join the round. You should now have a small circle of 10 HDC stitches.

Step 4: Increase Round

  1. Chain 1 (this does not count as a stitch), then work 2 HDC stitches into each stitch around. This will double the stitch count from 10 to 20 HDC stitches in this round. Slip stitch to the first HDC to join the round.

Step 5: Continue Increasing

  1. Continue in the same pattern, increasing the stitch count in each round. In each round, chain 1, then work 2 HDC stitches into the first stitch, and 1 HDC into the next stitch. Repeat this pattern all the way around. The stitch count should keep increasing by 10 stitches in each round.

Step 6: Measure and Continue

  1. Continue increasing until the beanie reaches your desired size. You can measure it by placing it on the head of the person you’re making it for. Typically, for an adult-sized beanie, you’ll want to continue increasing until you have about 60-70 stitches in the round.

Step 7: Straight Rounds

  1. Once you’ve reached your desired size, work HDC stitches in each stitch around for several rounds without increasing. This will create the body of the beanie. Continue until the beanie is the desired length. You can fold up the edge for a cuff if you like.

Step 8: Finish

  1. Cut the yarn, leaving a tail. Thread the yarn tail through your yarn needle and weave it through the stitches at the top of the beanie to close the hole. Fasten off and weave in any remaining loose ends.

And there you have it, a simple men’s half double crochet beanie! You can customize it by choosing different colors or adding embellishments like a pom-pom if you’d like. Enjoy your crocheting!
