Activity for Margaret

Our wedding is in a beach type environment, and not really formal, pretty laid back. The reception is held in a pavilion with picnic tables. I am trying to figure out how to word the "dress code". I don't want people showing up in suits and fancy...

This is what we are thinking about for favors, this is our very first one, so it isn't perfect, but you can see the idea that we are going for. They will be in our three colors and each will come with a tealight candle. What do you think?
