Sugar skulls are decorative skulls made from sugar, often used during the Day of the Dead celebration in Mexico. These colorful creations are typically adorned with bright icing, beads, and other embellishments, representing the spirits of deceased loved ones. The tradition of sugar skulls dates back to ancient Aztec culture, where skulls symbolized death and rebirth. Today, they serve as a way to honor and remember those who have passed away, blending art and spirituality in a festive manner.
