I love making my own jewelry!
It depends where you buy your supplies though, if you buy it from an expensive store (where you could get it cheaper), then I say it isn't worth it, unless you're just doing it as a hobby and not selling or something.
I have a bunch Ive made, but I dont have pics, Ill take some soon so you can see!
I mostly do things with big pendants and nothing too extravigant for the chain/rope part.
Depends what style you have, i guess!
