Great idea for a nautical shower! Purchase scrapbooking paper in the patterns of your choice from your local craft store, fold according to the directions below, and fill with candy of your choice. I'm thinking blue jelly beans!!
The flags in the middle could be assembled with toothpicks, hot glue and more colored paper. Either write or print on strips of paper your guests names, the date of the shower or a phrase from your theme - such as "Ahoy It's a Boy!".
