Wapsi SLF Prism Dubbing
Wapsi SLF Prism Dubbing is a synthetic dubbing made from specially processed multi-laminated fibres. The fibres reflect white light back in a separated spectrum, producing a prism-like, multi-colour effect on the finished fly. It is an effective way to add a changing visual accent to nymphs, streamers and other patterns that benefit from a distinctive body or thorax. The material dubs easily, so it can be applied directly to thread for a quick, controlled build. Work with a thin layer first and add more only where needed; a light brushing after twisting helps reveal the fibres without destroying the intended profile.
Construction and use
Use SLF Prism for bodies, abdomens and thoraxes when a synthetic, colour-shifting surface is part of the pattern. The available colour range supports many imitations and makes it useful for contrasting sections on a single fly. By varying how firmly the fibres are spun and brushed, you can keep the result relatively smooth or open it into a more pronounced, lively texture.
- Structure: multi-laminated synthetic fibres.
- Light effect: separated, prism-like colour reflection.
- Suitable patterns: nymphs, streamers and other bodies or thoraxes.
- Handling tip: apply a thin layer, twist it onto the thread and brush lightly to open the fibres.
