Oneida Jazz Stainless Steel Dome Plate Cover
Ah hah! Found it! These sold on eBay for only $5 a piece, and they are exactly what you need. The line is called "Jazz" by Oneida, and they look to be tough to find, but not impossible. This is a more simple plate cover -- more appropriate for home entertaining than silver with finials.
Mmmm..... breakfast in bed for the special person in your life who puts in extra effort in the bedroom. ....er... I mean office. They work very hard and deserve a weekend reward.... Great find by elvisgirl!
