I have just setup a profile at Twitter.
Twitter is a platform for sending short messages (140 characters) out to people who 'follow' you. You can use Twitter to build relationships with other people who share your interests and promote your handmade jewelry business. Learn how to use Twitter to promote yourself and your work, have fun doing it, and not being spammy.
With this being setup, I hope it will drive more traffic to the website and thus more sale for you! Cheers!
