Fortunately, I finished well before the kids woke up from their naps.
a thin, sharp knife
a large knife to slice the melon in half
a spoon to scoop out the melon seeds
Step 1: Prepare the melon
Using a crayon or some other writing utensil, draw Vs on the melon skin next to the cut edge. I used the stripes on this melon as a guide for the center of the Vs.
Using the thin, sharp knife, trace along the crayon, slicing just through the skin of the melon. Carefully shave off the skin of the melon from inside the V shape, leaving the skin intact below the line.
