The main character of a popular kids' television series, Thomas the Tank Engine train is a locomotive. He has a grey, circular face at the front and a blue body with red and yellow lining. The side of the locomotive displays the number one in bright yellow. A Thomas the Tank Engine mask will have a circular shape with Thomas' face. Strings or rubber bands will keep the mask over your face.
Visit the website of Thomas & Friends and click the "Activities" icon near the top of the web page. Browse through the pictures of Thomas the train in the wallpapers, posters, colouring sheets and birthday cards available on the website. Find one picture that you like the most. Right-click the image, select "Save image" and choose a location on your computer's hard disk to store the picture.
Navigate to the location on your computer's hard disk where you saved the Thomas the train image file. Double-click the file to open it with your computer's image viewer program. Crop the image so you only have Thomas' face in the image and enlarge it so it's roughly the size of your face.
Insert a 8.5- by 11-inch piece of cardstock into the printer feeder tray. On your computer, select print from the image viewer program window. You will get a print of Thomas' face.
Cut around the outline of Thomas's face and cut out Thomas' eyes so you can see through the mask.
Punch a hole on each side of the mask at the level of your ears.
Tie a string or a rubber band to each side hole. To wear the mask, place it over your face and loop the string or rubber band around your ears.
