Many thanks to williamgeorge for the tip below.

I just read your instructions for making a watermelon basket filled with fruit. I've made watermelon baskets and one of the problems I've encountered is liquid from the fruits collecting in the bottom of the "basket" which makes the fruit soggy. I corrected this problem with the last basket I made by putting "drainage" holes in the bottom of the watermelon after hollowing it out and before filling with the fruit. I then put the basket in a large oval roasting pan filled with ice cubes (to keep the fruit cold), and the water from the fruit drained into the pan along with the melting ice. This kept the fruit in the basket from getting soggy. Thought you might be able to use this idea.
