I found this while surfing the www, isn't it so cute?? The night my grandson and I made one, we didn't have most of the things to make it with, so I improvised. No cheesecloth, so we used gauze bandages. No wiggly eyes or electrical tape, so I used a black paint pen and a pencil eraser dipped in white paint. The directions are here at this site!
a styrofoam ball
black electrical tape
cheesecloth cut into 2" strips
This was very fast and easy and my 6 year old grandson had a blast making one,so we plan on more for our Halloween tree.
