Adjust the size
So, you have a great hat, but it’s too big or too small. Here are some really simple steps to make the hat you love fit you better:
How to make it bigger
Boil a tea kettle or a pot of water on your stove to create steam.
Hold the hat in the steam top-down so that you do not get the hat band wet. Be careful not to burn your hands on the steam. Hold the hat in the steam for 10 seconds and then remove it.
Firmly press the hat down over your head. The steam will make the hat pliable, and it will reshape to fit your head. Wear the hat until it dries.
Repeat the steaming process as often as you need to stretch the hat to fit your head. You may need to perform the process a few times if the hat is very tight on your head.
A few methods on how to make it smaller
Wash a shrinkable hat in a washing machine (yes, we’re totally serious). Wearing the wet hat afterward will let it conform to the proper size.
Put foam hat tape inside the hat. Add the foam hat tape as needed until the hat fits snugly.
Wear a wet hat on your head to let it conform to the proper size, and just wear it until it dries to fit you- although you may need to leave a bit more time (and patience) for that!
