Funprint pumpkins are super-easy to do. I have jack-o-lantern faces on all of mine, but, of course, you don't have to. The first one is just three thumbprints in a row and then index prints on top to make the leaves. To make the cat you do to index tip prints and embellish.
A single horizontal thumbprint also works great as a pumpkin.
If you are a little wishy-washy, the two thumbprint pumpkin is the way to go. Not too big or too small!
