You will need:
1 string of skeleton lights (lurking about your home)
2 6" long craft wire (I used a 26 gauge)
2 skeleton from said lights (with working parts)
2 light bulb socket
2 earring hooks
(I only used what I had on hand. If you have other supply's feel free to use them)
Make sure you have two complete skeletons with complete body parts
Carefully unscrew body from head
Use wire cutters about 1/2" above the skeleton head to remove it from string. (do this for both skeletons)
Remove light from head (should fall out)
Remove light from socket
Pull out old wires from socket. (use pliers)
Cut two strands of 6" craft wire.
Feed wire through top of light bulb socket. Bring it through and up back to the top. I wanted to reuse the socket so the skull would have a tight fit. (It did add some weight but not that much)
Thread socket through skull. (should fit snug) Pull up loop and carefully round it out.
Add earring hooks
Attach your body to the head. (should be a tight fit)
Giving me the chills I dare say.
