When buying this type of marabou, it comes loosely in a bag. There is some still floating out there that is on a patch called chickabou, which has way better selection. This stuff in the bag has a bunch of junk that you will weave through just to find a good pair to match.
Start your thread in the front and wind back to the bend. Once you have selected two and have matched them up you are ready to tie them in. I like my tail to be a little more then the whole length of the hook shank, and to be has bushy as you can make it. Wind forward like you see in the picture. I like to incorporate the excess along the shank for durability and it gives it just a little bulk on the hook shank. I stop about a third up the hook shank, where my head will be tied in with beaver hair.

Trim the excess. A little trick I started doing. I twist the stem of the marabou before making the cut. I wind back to about the middle of the hook shank. Tie in the polar chenille and wind back to where you meet up with the tail. Wind up to the stopping point, where the head will be tied in with beaver. Trim the excess.

Select about 10 strands of the rainbow flashabou and wind them around the thread, then tie them in. Now you have a total of 20 strands for your first flash wing. Notice where I make the cut, I like it hang off the back about a whole length of what the tail is.

Select 6-8 strands of the ocean green flashabou and repeat the same step. Once you have tied them in, wind a little on top of the flash forcing it to lay down and not sticking up.

Wrap the wire up. You don’t want your first wrap to be too tight or you will cause your wire to shift to the side of the hook shank. Then after the first turn you can add more tension as you make your segmentations up. I do about five keeping the segments evenly spaced. Tie down the wire and move it real fast back and forth. It will break from it getting hot. If you cut it with scissors more than likely you will have a little tag showing (and will dull your scissors over time).

Wind around making each wrap side by side and palmer the hair back as you make each turn. Now if you have too much in the loop you won’t be able to wind it all in and you will have to tie down where you ended up and cut the excess. This is ok, but the goal is to measure enough in the loop to not have this problem occur. Might take a few times, but you will get it down. Whip finish and glue the thread head with gloss coat.

I tie these in several colors so the sky is the limit. The reason why these flies are so important is if they don’t hit the lead fly because of the color or size this flashy smaller one sometimes does the trick. They turn right around and this one is in front of their face. What do they do, open their mouth and hit just because. It works like a charm. Good luck and let me know how you do. It’s also a great night time fly on Taneycomo when the moon is out.
