What is Wapsi Thin Skin?
Wapsi Thin Skin is one of the most widely used materials for creating realistic shellbacks and segmented bodies on artificial flies. The ultra-thin vinyl film is flexible enough to wrap smoothly around the body while remaining durable enough to withstand repeated casting and fish strikes.
The material is supplied on a paper backing, allowing clean and precise cutting into strips of any desired width. Once the backing is removed, the transparent film ties down easily and stretches or compresses under thread or wire, producing well-defined, natural-looking segmentation.
Wapsi Thin Skin is suitable for an enormous range of fly patterns, from classic nymphs and Gammarus imitations to modern shrimp, crab, streamer and saltwater flies. Its realistic appearance and ease of use have made it a favourite among fly tyers worldwide.

FLYFISHING.BG RECOMMENDSCut your strips while Wapsi Thin Skin is still attached to its paper backing for perfectly straight, consistent widths. After tying it in place, add fine ribbing and finish with a thin coat of UV resin or clear varnish. This enhances durability while emphasizing the material's transparency and creating a beautiful three-dimensional effect. |
