Paint your entire pumpkin green. You may need two coats.
Styrofoam pumpkin
Draw hair on with a pencil or black sharpie. I like to have an outline so that it's easier to paint.
Paint the hair on top of the pumpkin with the black paint.
Black acrylic paint
Use white, green and black craft foam to cut pieces for the eyes.
Craft foam
Assemble the eyes and glue with hot glue. Attach to the front of the pumpkin
Use black craft foam to cut a mouth. I went a little rogue and made mine different from the card. There's no right or wrong way so make it the way you like. Use white craft foam to make teeth and glue them around the mouth.
Finally, take a permanent marker and make stitches around the eyes and mouth. You can add them to the side of the pumpkin too if you like.
Now you have an amazing Frankenstein themed pumpkin to add to your other Halloween decorations!

Notes
We used a faux pumpkin from Dollar Tree but this craft works just as well with real pumpkins.
Use mini pumpkins for cute baby monsters!
If you're using a large pumpkin, you may want to save time by painting it with green spray paint instead of acrylic.
