You could decorate it easily with some little flags and some bamboo skewers.. . . .
Someone make this, OK?
"I designed this paper rainbow with the purpose of using it for a place card on St. Patrick's Day. I've found that my youngest is more enthusiastic about setting the table when she can make the place cards, fold the napkins in cute shapes and pick out a centerpiece (usually a toy). It makes the entire process fun and hopefully she learns where the utensils go in the process."Here's her link to the rainbow place card. All you have to do is print it out. Older kids can color it and cut it out and put it together.
