I would like to sell jewlery on a party plan to make extra money?

why not? go for it.

better try it with T-shirts at [email protected]

That is so Cool. You should go for it, follow your heart and go after your dreams. Sometimes you have to start with stuff you know. It will happen as long as you believe in your self and know you can do it....

I have heard that making your own jewelry can mean extra income.

Good luck, if you had freinds you wont after selling them the cheap jewlery!
