Yes, that was me when I first started, and almost every time I make a piece of jewlery! If you are making to sell, I would suggest hosting a show in your home and inviting friends, neighbors etc. Your confidence will come when they actually purchase your jewelry!
Also, wear your jewelry, and when someone asks about it don't be shy about telling them you made it.
When making your jewelry, slowly add in new components that may be a little less conservative. Experiment with different color combinations and different textures. Look at the inspiration pages on sites like Fusionbeads.com, Firemountain Gems and other bead vendors. Also, start looking at the webistes of the members of these forums for some great inspiration so you can eventually step out of your comfort zone.
Don't forget to show us some of your work! Alice
