Students created their own decorative Sugar Skulls using paper mache paste. What is the meaning behind the Sugar Skull? The Day of the Dead is a holiday celebrated in Mexico on November 1st. Sugar Skulls are a part of the holiday tradition that have been made since the Colonial Period of the 18th century. Each sugar skull represents a departed loved one and is usually placed on an altar — an ofrenda — or even a gravestone as an offering to the spirit of the dead. Sugar skulls are often decorated with the person's name. The folk art style of the sugar skull features decorative patterns and bright colors and are a lot of fun to make.
