I make custom baits all the time, it’s easy
here’s how I do it
get a bait I like, then a piece of wood about the same size
file sandpaper etc
then I start shaping the bait trying to make it look like the original.
then when I get it shaped it looks nothing like the original, so instant custom bait.
my painting is pretty much the same so instant custom paint job.
imitation is the greatest form of flattery. I just wish I could do it.
