Also to add to prestons list marabous are easy to tie too. Tie in marabou and wrap it on the shank and then do a different color, etc.

Popsicle pretty easy to tie
Frist color Orange marabou, I usually start half way up the shank.
Next color Red in front of the orange and about half as much.
Head finish off with a purple hackle.

Of course you can always add crystal flash etc.

Black is always a good color to start with too.

www.flyfishusa.com has a lot of pictures of flies if you want to see them.

Have fun. Steelhead are addictive.
