Here is a picture of a 3-wire copper john that I tied last summer. I have no clue why I did not take a picture of the fully complete and trimmed fly, but this is what I shot. BTW, I tied 12 of these flies and have one left. They worked about as well as most of my copper johns in various single colors.
This is the same chartruese,red, and black variant that ive been tying for a couple of seasons now. GREAT alternative when the trout have been educated to standard ''Johns'' dont you think? Just thought it was neat to see the 3-wire ''RASTA-JOHN'' I throw with much success on the Upper North Platte River in Wyoming! Great minds think alike!!!
