If your that stuck and money is certainly an object then do what a good ol boy/redneck would do,
grab hook,
squeeze large split shot on hook near eye
tie on some purple or pink marabou with elastic band or magic thread
go fishing, it works great,...... it really is that simple.
Suther: by all means try this idea out, but seriously I would just buy some proper damn jig hooks. Split shot tend to loosen, twist, ride down the hook, etc. Plus look at a jig hook...the eye is usually bent at 90 degrees to the hook. A standard octopus/salmon hook will NOT fish like a proper jig hook. That being said the hook + split shot idea may just work so by all means try it.
Nail polish works fine for painting. My gf gave me a bunch she didnt use plus i bought some from the dollar store. Id do a final coat of hard clear coat like sally hansen hard as nails. I prefer the metal bead and pin jigs as they dont get chipped up like the painted lead heads.
To save money here's a tip...if you have a jig that has been ripped up by fish dont toss it...put it in your vise, cut the materials off with a razor, and tie up a new jig! Sharpen hook at the same time and maybe even paint head a new color. Ive tried adding stick on eyes, sparkles, combos of paint colors dtc. I keep reusing my jig heads until either it breaks off on a snag or a fish.
If youre getting into jig fishing I would buy a dozen or so jig heads, some basic materials to tie up some jigs in colors/materials you like, and cut/retie any jigs that get ripped up.
