Halloween decorations are a popular way to celebrate the holiday. Common decorations include webs, skulls, spiders, skeletons, bats, and jack-o-lanterns. Webs are made of thin, sticky threads, often used to catch insects. Skulls are often associated with death and are often used as decorations. Spiders are eight-legged arachnids that can be found in many places. Skeletons are often used to represent death and are usually made of plastic or paper. Bats are small flying mammals that are often associated with Halloween. Jack-o-lanterns are carved pumpkins with faces that are lit up with candles. All of these decorations are popular choices for Halloween celebrations.
