I've been making these almost three years and yes, they do catch fish. Main colors resemble bait fish like bluegill , green sunfish, etc. that bigger fish eat. When I tie I use similar colors in the jigs.
I caught the white bass my last trip to local river, just under 3#. Hair jigs catch everything depending on size. Mostly tying baits with fox lately, even caught two grass carp with them a couple weeks ago.
I agree with the others Jim, very nice work. My river is just now becoming fish able and those you sent me are slated for my next trip out. I went experimenting and did well last Saturday so now the light rods and the hair and feathers come out. I’ll post pics when I go.
