Bleeding marabou feathers

[Baldy]

Hi guys -

I am making some marabou bucktails and i am experiencing some bleeding in the marabou.

I have thouroughly rinsed the tails and I am still seeing the bleeding.

It is not a huge deal on most, but i am making some contrasting colors (black/white, red/white, black/yellow) and I dont want the colors to mix together killing the look of the baits.

I have run them through the washing machine multiple times, rinsed them over and over with hot water...I am at a loss.

Anybody have any ideas on what I can do to get rid of all the excess die and make sure these things are colorfast?

Any help is greatly appreciated.

Thanks -

Luke
