Oh, I love a nice vintage tray. I always look for them in my travels. They are useful for so many things! Plus if you put everything on a tray, you can just pick up the tray and dust the table underneath it. I look for mid century Japanese trays in plastic or lacquer, vintage tin trays by Daher, depression glass (like this pink one below), porcelain, brass and (of course) I love a nicely painted Tole tray!
I have some trays for sale in my Etsy shop and more to be listed soon!
