Does anyone in the city know how to make jewelry? And have the patience to teach someone how to do it? Cause Mantis needs to do a thing.

a few of the jojocast talked about having a shop for that but i can't think offhand if we ever got a shop or anything

kakyoin can make earrings and pendants though. especially if you like emeralds

That might be the best bet. Mantis needs to make a pendant by hand for the Emporium and he has never done that in his life.

easy

Learning how not to suck at arts and crafts!
