None of them are appealing. Maybe this will help you some. For a real white background try using some posterboard and placing it next to a window or outside to take your pics. If you are outside try taking pics when there is an overcast in the sky. If you are looking for an appealing background then try using scrapbooking paper. There are so many to choose from and you can find something neutral that will go with everything you make. Try to steer away from busy backgrounds as they will draw attention away from your product.
