BM08, don't know how much you know about flytying, but dressing trebles is really simple. Clamp treble in a vise (of some type, a flytying vise is probably best), wrap some flytying thread on shank of treble, stoppingnear the bend of the hooks. Attach some hackle feathers (I prefer to use saddle hackle because of their size) or hair of choice. Wrap down securely, tie off, apply some zap-a-gap ca. and you're in business. This is much cheaper than buying dressed trebles. If you have a fly shop in your area, they can certainly help you with the materials. If I can answer any questions, please ask. Hope this info helps.
