Paint the entire bed red, green or purple, depending on what your favorite team's colors are. Paint isn't required, but it can make the bed stand out more. You can skip this step if you don't have a headboard and if the bed sits on a bed frame only. If you do paint the bed, allow the paint to fully dry before making any other alterations.
Place soccer decal stickers all over the headboard and sides of the bed. These stickers come in many sizes and colors. Feature regular black- and white-patterned soccer balls, or showcase white and purple or white and red patterned balls. You may want to also feature stickers that spell the word "soccer," or showcase team symbol stickers on the bed.
Place soccer-themed bedding on the bed that features soccer balls, players, team colors or other soccer-inspired patterns.
Adorn your bed with round pillows that resemble plush soccer balls. Pair these pillows with other square-shaped pillows that match team colors.
Place a round rug that resembles a soccer ball on the floor next to the bed as a finishing touch.
