After tying a few of these as gifts, FB2B decided to add the Polar Shrimp to our Salmon fly collection.  We use orange bucktail to form the tail.  The Polar Shrimp's body is made of orange chenille with holo tinsel wrapped along the outside.  Lastly, orange saddle hackle forms the collar.
 
Hook size:  Salmon/Steelhead size 4 (black).
