Hi Lorraine,
I've had a bit of success on e-bay, sold a few items of jewelery. (Proper hand-made items, not the cheap tacky stuff) I'd say give it a go, but take a few precautions. First, to keep your costs down, don't use 'Reserve Price', it really bumps your listing fees up. Just start the bidding at your lowest acceptable price, and maybe offer a 'Buy it now'.
On the security side, I'd suggest a PayPal account, connected to a bank account that you use for e-bay only, and keep the minimum balance in this. That way if any body does get in to it, they don't get much. Use strong passwords, and don't enter any personal details you don't need to. (Some are needed to open a PayPal account)
Good luck,
Dave.
