Halloween decorations include webs, BATS, skeletons, SKULLS, and jack-o-lanterns. Webs are made of spider silk and are often used to decorate doorways or windows. BATS are a common symbol of Halloween and are often hung from trees or ceilings. Skeletons are usually made of plastic or paper mache and are used to create spooky scenes. SKULLS are often carved out of pumpkins and placed on porches or in windows. Jack-o-lanterns are carved pumpkins with faces that are lit up with candles or electric lights. All of these decorations are used to create a festive atmosphere for the holiday.
