Hi, what kind of jewelry, there are all sorts of different types. I noticed you posted this a long while ago but figured if you are still interested you will read this. I currently make everything from fine silver jewelry to hemp crafts. All you really need to learn how to decorate clothes and bags are stuff that interests you. Say you have a blank tshirt that you think needs a little pizzazz. Just put a stencil on it and paint it, same goes with decorating bags. You could also use bleach on a dark shirt too, to give it a nice tie dye effect. There are plenty of craft tutorials on this site and others. Just go with what interests you or else you will get bored of it really quick.
