I also designed my escort (seating) cards on Microsoft Publisher. I wanted to incorporate a peacock feather in my design, and I used the same metallic card stock I used for the invitations. Then, I got them printed and cut at LP Printing for a pretty decent price! I think the single green peacock feather brought our theme together well =)
Here's another picture of the table numbers in action along with the centerpieces and linens...
