They came in perfect for a fall themed wedding last month. I cut slits in the top of each cork with a small saw and then pushed a little round map pin into the back to make them stand up. You could also saw the bottoms to make them flat, but the pins were a lot easier.
To make the escort cards, I bought cream colored business cards at Office Depot and printed names and table numbers on them using Microsoft Word.
Ok, well actually my husband did most of this, but you know...same thing :)
