Whether you're dressing up as a tortoise to be in a school play, for a costume party, or as part of a presentation, making your costume does not have to be something to stress about. With a few basic craft supplies, you can have a tortoise outfit in no time.
Trace two large ovals on two different large pieces of cardboard. Make one oval smaller than the other. The small oval will be used for the bottom of the shell, and the larger oval will be used for the back, or top part of the shell.
Place both ovals on top of large pieces of felt, and trace their outlines with pencil onto the felt. Add 3 to 4 inches around the outside of the outline, and cut out the fabric ovals. This gives you extra material to overlap on the cardboard when gluing the felt to it.
Glue the fabric to cover the ovals with a hot glue gun. Allow the glue to dry completely, and use a marker to draw designs on the bottom and top parts of the tortoise shell.
Cut strips of fabric to go over your shoulders, and attach them to the tops of both ovals either by gluing them or stitching them in place. Attach the ends of the strips to the underside of the ovals.
Put on the long-sleeved shirt and green or brown trousers. Paint your face with your face paint to make yourself look more like a tortoise. Drape the shell of the costume over your shoulders.
Add accessories to your costume, depending on the type of tortoise you want to dress up as. For example, if you dress up as the tortoise from the tale "The Tortoise and the Hare," you may want to add some running gear like sweatbands and a water bottle to complete your outfit.
