P-noid:

I have been customizing my warts for years. I replace the trebles wit a 3 bead chain w/split rings and use gammy 1/0 siwash hooked to the forward eye. They don't get hung up nearly as much and the gap on the siwash bites in real well.

Get yourself some paint pens at a craft store and experiment. If you screw up too badly, wipe or dip them in lacquer thinner and start over.
