Wise storage of your flies over the winter will assure they will be in good shape when you are ready to fish in the spring.
Dry flies that are matted and have mashed hackles should be carefully steamed over a teakettle with a small strainer or long forceps, being very careful not to get burned by the steam. Lay these aside to dry thoroughly before storing them in your fly boxes.
Streamers, nymphs and surface bugs may need to have grass or leaves pulled off them and old pieces of mono trimmed from their eyes.
Store your flies in their boxes in a dry area and they will be ready to use next spring.
