The following procedure allows a fluorescent bead to be added into a marabou tail. This gives added attraction and gives the fly a different kind of movement to the standard tailed versions. This method is mainly used on long tailed lures. Give it a try and compare.
Take a bunch of white marabou and pinch away any excess fluff using your thumb nail and fourth finger from the end that will be attached to the hookshank. Now tie in the marabou with the thread. Try and keep the body as uniform and thin as possible.
There's a slight twist to the tail. The tail is made up of three sections of marabou. The lower section that has just been attached (above), the middle section which contains a fluorescent bead and an upper section. To create the middle marabou section, take a small bunch of marabou and strip away any excess fluff again. Now wet the ends that will be secured to the hookshank. Place a fluorescent bead onto a bobbin threader and then place the wet ends of the marabou through the bobbin threader. Now push the bead forward onto the marabou so that you have something similar to that in the picture above. Take a wooden cocktail stick or something similar and apply a little superglue gel to the end of the cocktail stick and then apply superglue (Sparingly) to each side of the bead on the marabou tail. (The bead will eventually wear off but I find the added attraction on this pattern is well worth the effort fitting the bead).
