When my 19 year-old daughter Sarah sees peacock feathers, she sees pretty skirts for cornhusk angels. To my 7-year-old daughter Autumn the same feathers represent pieces needed for cute little dolls. To me, peacock feathers a represent jig or fly material. The iridescent green and purple strands make wonderful tail material, and also work really nicely for wrapped bodies. I use them in both smallmouth jigs and trout jigs.
Normally the peacock complements other materials, adding a little flash to a black or gray hair jig or a deeper green to an olive marabou jig. The jig above is actually all peacock.
It also works nicely for me because I get all the materials I need from Sarah's remnants. She needs the full end of the feather with the prettiest colors, and she always end up with pieces that have several strands still on them She would throw those away, so I gladly move them to my tying area. Autumn's use falls in between. She likes the full pretty feathers, but she just likes making things, so she makes her dolls, enjoys them for a while and then takes them apart and give the feathers back to Sarah!
All this peacock talk makes me want to go trout fishing.
