Kamasan B170 size 14 hook. Uni-thread 8/0 grey. Few pheasant tail fibres dyed heron grey for the tail, body & wing case. The body is ribbed with gold wire. Dubbed Muskrat fur is used for the thorax and is picked out with a needle to create the legs.[Note – I prefer to tie this nymph with grey goose feathers but I appear to have run out!. Frank Sawyer produced two versions of a nymph using grey goose]
