If it fits loose. If the favorite hat is a bit too wide or you need an intermediate size, just put the cork strips under the lining. With the set you can narrow the head size by about 1 cm. Depending on the shape of the head, the bands are either pushed sideways or at any point under the inner band and hold without further aids. Sewing or gluing is also possible, so that nothing falls off when putting off the hats.
