Was my approach to repairing stripped holes in a door jamb appropriate?
Paper towels and glue are both relatively weak. The best thing is wood plus glue. Fortunately most of us have some right sized pieces of wood handy in the kitchen:
Toothpicks
Clean the hole. Put in some glue. Stuff the hole with toothpicks (possibly dipped first in glue - depends on how big the hole is and how much glue oozes out as you stuff in the toothpicks). Cut off the ends sticking out of the hole. Let dry.
It is also a good idea to use longer screws if you can. But match the head of the existing screws so that the screws match the holes in the hinges.
