It takes a certain sort of person to want to draw a frog. Whether you're drawing or doodling frogs, it suggests a quirky, smart mind that has an affinity for humor. Frogs appear quite a lot in cartoons for just this reason; there's something about that blas¡, even blank expression that makes us want to poke fun.
If you haven't guessed already, I have a thing for frogs. The natural curviness of them makes for very interesting lines and designs. We have a gold frog ornament sitting on our mantlepiece (the only ornament on the mantelpiece) and I have a large, full-sized bullfrog ceramic piece that I've have since I was five. It was originally my mother's,
but I loved it so much she gave it to me.
