If you want that special items to set off a dinner table you could design a special one of a kind napkin holder and for around $8.00 a piece the folks from Shapeways will take your design and build your custom napkin holder.
If your not a 3D artist they have a software application called the Shapeway Creator that lets anyone design complex objects that can be turned into a product. See the cool stuff that can be designed and made by watching the video.
