*To stick the eyes, I grab a toothpick and dip it into the melted chocolate on the bottom of one of the pumpkins I've already placed on a cookie. Get enough to dab onto the back of a candy eye, then stick it to the top of the pumpkin, ghost, bat, etc. Once they cool, you won't even be able to tell you dipped a toothpick.
Just in case though, I dip it into one that's already a bit wonky or beat up looking.
