3 Baby Hat Sewing Patterns

Keep up with your baby's abundant wardrobe by sewing hats to match each outfit. While winter hats are common, babies also need summer hats to keep their faces and heads protected from the sun. Try one of these designs to sew a lovely and useful hat for baby.

Three Quick Baby Hat Patterns

Each of the following hats is sewn using a 1/4-inch seam allowance throughout unless otherwise stated, and can be completed in under 30 minutes. The amount of cut yardage has been given in the supply list but scrap fabric can also be used. If your fabric feels too light to hold the shape of the hat, cut additional pattern pieces using fusible interfacing. Simply iron them to the back of the fabric pieces and sew as instructed.

Sizing Tips

The size for each hat will give you a loose to snug fit during the growth period stated for a baby's average measurements. Adjustments to the hats can be made for a better fit during the growth period.

  • A simple way to temporarily adjust the hat is to fold a small section at the back of the crown and pin with a safety pin. This will provide a longer period that the hat will be wearable before being packed away.
  • Another temporary fix is to gather a small section at the back of the crown using needle and thread. As baby grows, clip the thread and gather again, accommodating the larger size.
  • A permanent adjustment could be done during construction of the hats. The sun hat and the ball cap adjustments can be done at the bottom of the crown pieces. To figure adjustments, measure the circumference of your baby's head. For the sun hat, divide the total by six and add 1/2 inch (total of two seam allowances). Change the bottom of the crown pattern to your new measurement and adjust the sides of the pattern to fit. For the ball cap, divide the baby head measurement by two and add 1/2 inch. Change the bottom of the crown pattern and adjust the sides. The bonnet should need no changes to the pattern.
