Alright, ours is SIMILAR to this pumpkin- not "dead on" perfect, but Hailey likes it and that is all that matters to me. When we were at Grandma's this past weekend she got them each a small pumpkin of their own (because apparently it's not enough that we grew 15+ in the backyard). Anyway I convinced Hailey to get a white pumpkin so we could turn it into Hello Kitty. Now the original bloggers witch hat is nicer- because it's fabric. We didn't have that and had to improvise with construction paper.
This is really self explanatory: we took black and yellow sharpies and colored Hello Kitty's face onto the pumpkin. Then we cut out the hat and ears and tapped them onto the pumpkin.
