...you can't use clocks (vintage or new) as table markers?
***Had to add a little update in after Jessica's comment ;-))) I intially thought the same thing...would only work if you have 12 tables. But remember you can set it at the 15, 30 and 45 minute increments too! Or get really into it and set the clock at specific times that have meaning to you!
