Fly Tying Wire
Wire is one of the most important yet overlooked materials in fly tying. Most tiers wrap it around the hook shank without much thought, then wonder why their flies don't perform properly in the water. Here's how to use wire strategically to create flies that fish better.

Understanding Wire Types and Applications

We carry an extensive selection of wire types, each designed for specific applications:

Lead-Free Heavy Weighted Wire (Semperfli): Best for adding significant weight to nymphs and streamers. This environmentally safe option provides excellent sink rates without the toxicity concerns of lead wire.

Round Wire (0.1mm, 0.2mm, 0.3mm): Copper and brass options are perfect for ribbing and light weighting. The different diameters allow you to match wire size to hook size.

Ultra Wire (X-Small to Medium): Extremely fine metal wire ideal for delicate ribbing work on small flies. Available in multiple colors for matching natural insect segmentation.

Flat Colour Wire: Provides subtle segmentation without the pronounced ridges of round wire. Excellent for realistic nymph bodies.

More Effective Wire Use In Fly Tying

Weight Distribution Technique

Stop wrapping wire randomly around the hook shank. Instead, use graduated weighting:

  1. Thorax Area : Place 60% of your wire weight in the forward third of the hook shank
  2. Mid-body : Use medium-gauge wire for transition weight
  3. Tail Area : Minimal or no wire to allow natural movement

This creates a head-heavy fly that rides properly in the current and triggers more strikes from trout.

Specific Patterns:

Mayfly Nymphs: Concentrate weight behind the wing case area using Semperfli's lead-free weighted wire. This mimics the natural's swimming posture.

Caddis Pupae: Distribute weight more evenly but keep the heaviest section just behind the eye to simulate the gas bubble that helps pupae reach the surface.

Stonefly Nymphs: Use heavier wire throughout the body, with maximum weight at the thorax for fast-sinking presentation.

Ribbing Techniques That Work

Variable Spacing Method

Traditional ribbing uses 5-7 evenly spaced turns. Advanced fly tying wire technique varies the spacing:

  1. Start with tighter turns at the tail (3-4 wraps close together)
  2. Gradually increase spacing toward the thorax
  3. This creates visual depth and makes flies appear more lifelike

Counter-Wrapping for Durability

After building your body material with clockwise thread wraps:

  1. Wrap ribbing wire counter-clockwise
  2. This prevents the wire from cutting through body materials
  3. Your flies will last significantly longer

Use UNI Products or Wapsi ultra-fine wire for this technique on smaller flies.

Working with Flat Wire


Shadow Line Technique: Vary your wrapping tension to create areas where the wire sits proud of the body and others where it nestles into the material. This produces subtle light reflection underwater that mimics natural insect carapaces.

Segmentation: Flat wire creates more realistic segmentation than round wire, especially effective on midge larvae and small nymph patterns.

Product-Specific Applications

Ultra Wire Applications:


  • Brassie patterns: Use Brassie-specific sizing for hooks 18-22
  • Midge larvae: X-Small Ultra Wire creates realistic segmentation
  • Small mayfly nymphs: Medium Ultra Wire for proper weight-to-size ratio

Lead-Free Weighted Wire Uses:


  • Fast-water nymphs: Heavy weighting gets flies down quickly
  • Streamer heads: Concentrated weight creates proper swimming action
  • Euro nymphing: Precise weight control for competition-style flies

Round Copper/Brass Wire:


  • Traditional wet flies: 0.2mm provides classic appearance
  • Soft hackles: Light ribbing that doesn't overpower delicate materials
  • Emergers: 0.1mm for minimal weight addition

Color Selection Strategy

Wire color serves functional purposes beyond aesthetics:

  • Copper Wire: Mimics the natural copper-green tones in caddis larvae
  • Silver Wire: Replicates air bubbles in emerging insects
  • Gold Wire: Matches many mayfly nymph colorations
  • Red Wire : Provides a strike trigger in certain water conditions

Environmental Considerations

Lead-free alternatives aren't just environmentally responsible, they're often superior performers. Modern alloy density provides better sink rates with less bulk, creating more realistic fly proportions.

Our selection of lead-free options ensures you can fish any water without environmental concerns while maintaining performance standards.

Common Mistakes to Avoid


  • Over-weighting: Too much wire creates unnatural fly behavior
  • Wrong placement: Weight at the tail end kills action
  • Inconsistent spacing: Uneven ribbing looks amateurish
  • Wrong wire size: Match wire diameter to hook size

Wire is about a lot more than 'just' adding weight; it's about controlling how your fly behaves in the water. Strategic placement, proper technique, and quality materials will transform your flies into effective fish-catching tools.
