make sure you dont have too much going on...too busy of a background, it will take away from your products. How about just a plain background like white or black from felt, fabric etc... to make your items pop? Or how about a nice soft print sheet something very suttle & then put boxes under it to create demention and different levels for your products to sit on. how how about a plain background and maybe some flower pots like terricota and putting them upright, on their sides very simple & just a slight added feature to your products.
