Organizing your fly boxes makes it easier to find specific patterns while you're on the water. In the December 2004 issue of Fly Fisherman, Rene Harrop shares his fly-box system and explains how to create one customized to the type of hatches you expect to encounter, displaying four of his fly boxes as examples. For those interested in the specific flies contained in the boxes, below are the boxes with a list of the flies.

Features
Pondering PMDs
The Master's thoughts on techniques and tactics for these small ghosts of seasons past.

Blue-winged Olives
Fall Baetis hatches provide the last chance of the season to catch trout on top in the West with mayfly imitations.

The Little Drakes of Summer
Big Trout on pressured water are never suicidal, but there is something truly uncommon in the way they respond to the small, stout drakes of summer, Drunella flavilinea, or Flavs.
