What you will need:
Dollar store stuffed seasonal toy ($1.25)
A small plastic or Foam skull (I used a 5.5" Plastic $1.50/ Pkg of 2)
Hot Glue Gun
1) Find a stuffed toy
2)Find a skull that will fit into the "face"
3) Pierce a small hole in the face and cut out the material (Cut smaller than skull, easier to cut more away than to glue more)
4) Remove stuffing from head area
5)Place skull into face and take note of where the fabric hits so you know where to put hot glue.
6) Hot glue material to skull, I recommend all the way around stretching the material to fit snug on the skull.
I am putting a few of these around my house, face down, during a haunted house party. Innocent from one side and unexpected from the other.
