All you will need are the fruits that you want to use, a container of some sort, some styrofoam, and some skewers. In mine i used strawberries, pineapple, grapes, honeydew, and cantaloupe.
Step 2: Cutting the pineapple
The easiest way i could think of was to draw it out. cut the pineapple to make the shapes of what you want. I did flowers and hearts.
Cut your styrofoam to fit your container then place it inside the container. Then skewer the sticks into the foam. Place the fruits on the skewers in whatever design you want. I've seen many variations (in baskets, vases, trays). Just get creative :) I went with the typical Flowers in a vase design.
