My family has the tradition of "visiting" another country for a day by decorating, wearing costumes, having food from that place, and studying it beforehand. This year, we didn't really "go" anywhere because we did historic Texas. It was a lot of fun. Here's our table, with the children's posters and the life-size longhorns behind it.
Laura decided she was going to be a cowboy, so that gave us four "couples." The cowboy boots even made her taller than Becca!
