Thread the plastic in jig slowly, take your time to adjust to make sure everything is centered. Push the tip of the hook through the marked spot when you get there.
Jigs should be easy. Trying to thread big plastic swimbait like these only the jig head nicely is a bigger pain in the ass but I can do it easily now with some practice (with trials and failures during practice)
