Fourth, now pull the headband outward after each rotation, still rotate the hat so you get an even expansion.

Fifth, measure the headband and make sure the new size is larger and will fit you. If not, keep stretching. Allow the hat to dry only after it fits on your head.

One word of warning, do not use a hairdryer or a clothes dryer to try and stretch the hat. Those items will shrink the felt.

Fill a sink or tub, large enough to hold the pants while they soak, with cool water and add a little Woolite or other wool cleaning product and a cap full will do. Soak the pants for about 20 minutes without stirring the water. Just make sure they submerge and stay that way.

Once the soaking time is over, squeeze the excess water out of the pants and hang the pants in a pants hanger by the hem. Follow the crease so they retain their original shape. If there is no crease just zip and button the pants and then fold back pocket to back pocket. Hang by the hem.

Before they are dry, try the pants on and if they are still a little tight around the waist, let the seam out a little to accommodate your size.
