A friend in Ireland said something to me a couple of years ago, which got me thinking about weaving with wire. Why bother? Well it makes slimmer heavier flies. Using wire uses about 20% more wire than winding a similar body from wire. I usually find that if I want weight then I want as much as I can get without huge bulk.

The wire I use are from beading craft stores. Usually 0.2mm or 0.3mm. UTC wire is were I started but it is about 20x the price of the wires I now use. With the 0.2mm wire I can happily go as small as size #18. On larger flies I twist two strands of wire twisted together, often of different colours. To twist the wire I use a dubbing whirl on short lengths, or a drill with a cup hook in the chuck for longer lengths.

When you start you need to make a decision on the profile of the fly body you want. It you want it wide and flat then the strands of wire are tied in to either side of the hook. It you want a deeper slimmer profile then tie them side by side on top of the hook shank. You can also put a tinsel under body on before weaving for a glint from inside the fly.



Those are Czech nymph type flies make with twisted strands.



The same again with single strands.

Weaving with wire is very easy as you don't need to maintain the tension on the strands, as you do in weaving with soft materials. It is really easy to do. All you need are two strands of similar gauge. Give it a go. Its the best way of tying slim heavy flies I've found.
