I've been looking for a butler's tray to use as a bar for quite a while. I posted an example of what I was looking for here.
This is my solution
I found a pair of butler's tray stands at the Ann Arbor Antique Market last month. After a workout with steel wool and denatured alcohol, I gave the already distressed finish a coat of stain in a walnut color. This darkened the finish just a bit. I replaced the cheap, lawn chair-type straps with leather. A purchased tray from West Elm tops the stand.
The latest edition of Lonny Magazine features a tray table similar to mine. I was interested to see what was on the tray. On my tray I have my favorite summer drink mixers on a silver tray along with an ice bucket, linen napkins and a bowl for nuts or olives. I'm sure I'll be changing the "scene" with my mood and needs.
