For Scuds & Mayfly Nymphs. 12 non-toxic silicone nymph backs, delivered with instructions.
Realistic Nymph Backs Scud is used to create durable and realistic backs on small crustaceans such as merles, shrimps and for imitation mayfly nymphs. Made of silicone, which makes them easy to work with and very durable.
Using the J:son system, you can tie realistic dry flies that leave a perfect impression on the water’s surface and are virtually unsinkable. Nymphs made with the J:son System have a natural silhouette and are taken for real insects. J:sonSystem flies are durable, so you can focus on the whole point of fly fishing, which is to fish.
When making wings, it’s possible to fuse a patterned wing material with a neutral one. This way, an air pocket is created between the two layers, increasing the fly’s floating ability. Regardless of whether your fly is used on the water surface, in the surface film or sub surface, the wings and wing buds will be very realistic in shape, color and structure. At the same time, they are extremely durable. The raw material for wings and wing buds consists of guaranteed toxic-free foil, and produces no harmful gas of any kind when burned. It’s approved by Swedish health authorities for use in the food industry. All J:son tools and materials are made in Sweden.
How to make wings
Trim excess material around the printed pattern (leave 1-2 mm for burning). Place in the appropriate wing burner and burn/weld the edges quickly with an open flame. You now have a perfectly shaped, realistic wing. The body of foam, the light weight and water surface tension all mean the fly will float like a dream.
Use double wing material when tying larger flies. This creates an air pocket inside the wing, enhancing floating capabilities.
Use a printed wing material and marry it with a neutral one. Trim excess material (leaving 1-2 mm for burning) around the printed pattern, place in the appropriate wing burner and burn/weld the edges quickly with an open flame.
You now have a perfectly shaped, realistic wing that contains air, which – together with the body of floating foam – makes the fly virtually unsinkable.
