"Eggstasy is a revolutionary product for tying egg-flies. Unlike standard egg-yarn, which involves spinning yarn, Eggstasy is built on a core which means you can simply tie it like a chenille. The other huge difference that sets Eggstasy apart from other yarns is the fibre itself. NX-Gen Fibres are micro thin and are designed to trap water, forming an almost slush-like texture when wet. Almost like a sponge. The fibres are also translucent which allows light to travel through the egg/blob - unlike standard Egg Yarn. NX-Gen Fibre has great movement, unlike egg yarn which remains static. In the water the egg looks almost life-like. Please note - we've photographed each colour in it's wet, slush-state because there is a 30% colour change when wet."
