Any tips for repairing dust jackets?

Sorry as I realize this doesn’t exactly have to do with a specific category, but I wasn’t sure of another place to ask this (delete if not allowed). I’ve had luck using a bit of tape on the back of my other ripped FL and coloring it in with a sharpie, but the cover was quite dark.

Does anyone have any tips or tricks for repairing damaged dust jackets? Not sure what to do with this one. TIA!
