Hedgehogs are nocturnal mammals found on every continent but North America and Australia. The trademark of a hedgehog is his spiny coat, which he uses as a last resort when attacked by predators. While many people dress as cats and dogs on Halloween, you can dress up as a hedgehog for something different. A hedgehog costume is a unisex outfit that both children and adults can enjoy. You can make a hedgehog costume at home with items picked up from your local craft store.
Purchase several A4 foam sheets in brown, tan, black and grey at your local craft store. Cut the sheets into 6 mm by 21 cm (8 1/4-by-1/4-inch) strips with a paper cutter or scissors.
Place a sheet of cardboard inside a brown oversized T-shirt. Begin at the bottom of the T-shirt and glue the strips of foam to the back side of the shirt with a hot glue gun. Leave about 6 mm (1/4 inch) between each strip and alternate the colours. Layer each row of foam strips on top of the next until you reach the top of the T-shirt. Remove the cardboard.
Turn a brown baseball cap backwards. Glue strips of foam to the baseball cap with the strips extending over the rim of the hat. Alternate the colours.
Draw a circle at the tip of your nose with black eyeliner, and colour it in.
Put on the shirt and wear the baseball cap backwards on your head. Complete the costume with a pair of brown trousers or tights and brown shoes.
