Previous Pinner said: A 25' spider web needs a big spider. So I hand carved from blue styrofoam the body. Then painted it with black latex house paint and made legs out of 3/4" and 1/2" PVC. The eyes are made from the cheap toys in the supermarket gumball machine containers. The cap was removed then inlayed into the foam. to back them I use 3M reflective tape so when you shine it with a flashlight it looks like real eyes. Then I added LEDs to all 8 eyes to make them glow red.
