I'd say just dive into the jewelry making process. What materials you use. How you do it. Where people can get your stuff at online/contact info.
I put bio/contact information at the end of each article for the writers. This is an example of what mine would look like:
Jennifer is 26-years-old and living with a left obstetrical BPI. She is located in San Francisco, CA. She can be contacted at example@email.com you can also find her talking on the UBPN.org forums as “Jennifer P.”
You can put as much or as little as you want in that area.
