How to Reblock a Cotton Hat

Cotton hats can be reblocked to achieve a new shape.

Hat blocking is the process of applying moisture, usually in the form of steam, to a hat to change the shape. Blocking can give a hat a unique style or can be used to make a hat fit better. Once a hat has been blocked, it is not permanently limited to that shape. A hat can be reblocked if it has been crushed, if it does not fit properly, or if you simply tire of the shape.

Things You'll Need

• Measuring tape
• Balloon
• Bowl
• Mannequin head
• Spray bottle
• Cotton cord

Instructions

1. Measure the circumference of your head at the level of your head where you would like your hat brim to sit. Inflate a balloon to the same circumference to use as a hat block for knit cotton hats. Find a bowl with a rim that fits the same measurement as your head and turn the bowl over. This can be used to create a rough hat block for sturdier hats.

2. Mist the hat with a spray bottle filled with cold water. The goal is to get the hat lightly moist, not drenched, so use a light hand and take care to get the entire hat evenly moist, including the interior.

3. Place the hat on your block, gently rubbing the sides of the hat with the palms of your hand, using a downward motion, to get the hat into place. Do not pull at the sides of the hat because you can pull your hat out of shape. Shimmy the hat back and forth if it is having difficulty getting into place.

4. Tie a cord around the hat where the brim meets the crown if you are blocking a hat that has a crown. This will create a sharp definition between the crown and brim. Press the cord down to make sure that it is even around the hat.

5. Shape the hat into the desired crown shape using your hands. This is the time to create creases or peaks in the crown if you desire. Shape the brim using your hands.

6. Allow the hat to dry on the block. Remove the cord and the hat after the hat has dried completely.

Tips & Warnings

• Purchase a styrofoam mannequin head to use as a block for sturdier hats if you desire a more precise fit. Cotton shrinks in heat, so if you want to reduce the size of your hat, use a steamer instead of a spray bottle.
