This is how I cut watermelon....

I could eat a whole watermelon in one sitting - seriously!

I find this to be the easiest way to cut watermelon!  These photos show a small round watermelon, however it works great with a large melon.

Cut it in half and slice it lengthwise and crosswise:

Perfect for little hands (or mine).  Easy peasy!

Very easy to grab a piece, or two or three!

And all the extra corner pieces?  Just cut away the rind and eat them up!
