I topped things off with some marshmallow peeps, and viola! A spring-time center piece that was quickly gobbled up!
Seriously, this didn't take much time at all -- from setting everything out, washing the fruit, cutting the shapes, and stabbing it on skewers before sticking it in the foam -- oh, and including clean-up! -- it took maybe 45 minutes. If you try this -- and do! It's so fun and easy! -- dip your fruit in a mixture of lemon juice and water before spearing it. It'll prevent the fruit from browning. I found the melon, and especially the watermelon, was pretty juicy and drippy, so you may want to cut those and put them on paper towels for a few minutes before spearing them. Use your imagination -- any free-hand shapes or cookie cutter shapes work great!
