Your items are very beautiful, and your prices are reasonable.
I also make handcrafted jewelry, and I have been doing Fall craft shows for about 14 years. I do beaded necklaces, earrings, and bracelets. Most are natural stone beads, Freshwater pearls, Austrian Crystal, and some glass. I never use plastic.
At the craft shows I arrange the jewelry in sets, but each thing priced seperately. If someone only wants the earrings I sell them just the earrings. I will still keep the necklace on the table that day, but I will make a notation in my inventory book that I need to make a new pair of earrings.
If someone ONLY wants the necklace, then I just place the earrings on the display that has only earrings.
As much as I enjoy the craft shows, it is extremely difficult to get out of bed by 6 am on a Saturday! I work my office job Mon-Fri.
Craft shows can be fun, but it is hard to determine WHICH ones are the better ones. Make sure you go to many craft shows as a customer to check them out.
