Palmering marabou is something I do every day. I make a ton of Alaskabou patterns, and Jay Nicholas ties up a nice variation of the Showgirl Alaskabou here. Just switch out the colors to create a ton of nice flowing steelhead flies.
Chartreuse + Black = Nitro
Orange + Pink/Red + Purple = Popsicle
Yellow + Black + White = Black Ghost
Hot Pink + Red = Candy Cane
Hot Pink + Silver Dr. Blue = Chum Candy
There are tons of variations a tyer can create. Switch the colors to target other species as well like pike or Bull trout.
