The pattern is offered in two adult sizes. The brim section has two sets of stitch numbers but in the body and crown sections the stitch counts are the same. The hat size, after the brim, is altered by adjusting the needle size. Shetland wool should be hand washed and rinsed in hand hot water. Wrap item in a towel or a very light spin in a washing machine to remove excess water. Stretch hat over a bowl of a suitable size and leave to dry.
