I store most of my flies in boxes with little cubicles. Later they may get transferred into the foamed fly box. The flies, especially the dries are often smooshed together over time. The hackles are askew and different than how they looked out of the vise. If one takes the time, steam can be used to resurrect those flies. It can also be used to spruce up fly tying materials. Here Don Bastian provides helpful advice on steaming feathers. Don has a very nice ‘wet fly’ site. There is much to be inspired by on Don’s site.
