Yoshi, the cartoon dinosaur, is a familiar icon for avid Nintendo players. The green and white character made his debut in 1990 in the game "Super Mario World." Throughout the years Yoshi has appeared in games, including "Super Mario Word 2: Yoshi's Island" and "Yoshi's Story." Making a mask that represents Yoshi the dinosaur adds a finishing touch to a homemade costume. Make the mask using supplies found around the house and at most craft stores.
Draw one large circle onto a piece of corrugated cardboard using a pencil and cut it out with scissors to form his trademark snout. Make the eyes by drawing the letter "M" with arched tops instead of points onto a piece of corrugated cardboard. Draw a line across the bottom of the "M" to finish the eyes. The eyes should be about 1/3 the size of the snout. Cut out the eye shape with scissors.
Place the cardboard cutouts of both the eyes and the snout onto a piece of lime green felt. Trace around both pieces of cardboard with tailor's chalk. Cut out the felt pieces with scissors.
Poke two small holes on either side of the snout cardboard piece using the point of a compass. Cut a piece of elastic that's long enough to securely fit behind the wearer's head. Thread the elastic through one hole and knot it so it stays in place. Thread the other end of the elastic through the other hole and tie the end in a knot.
Spread a thin layer of fabric glue on the back of the pieces of lime green felt. Align the felt with the cardboard pieces and press them into place. Cut two tiny ovals from black felt and glue to the snout to form Yoshi's nostrils. Create the whites of Yoshi's eyes by cutting two equal round shapes from white felt. Glue into place over the green felt so that approximately 1 inch of green appears above.
Place the eye piece onto a cutting mat and use a utility knife to cut round eye holes so the mask wearer can see. Press the utility knife down until it goes through both the felt and the cardboard.
Run a line of fabric glue over the bottom strip of the eye piece and press it to the back of the snout piece so it extends over the top. Allow 24 hours for the glue to dry before wearing.
