Space costumes are always appealing to children, especially adventurous children. To them space represents excitement and wonder, and it fuels dreams of being an astronaut or scientist. Costumes like this can also have an educational value; this version of a moon costume includes a T-shirt with the planets of the solar system on. Ask your child to help you make the costume and help him learn the names of the planets.
Fold the gold fabric in half and trace a circle onto it so that the edge of the circle is touching the fold of the fabric. This will create two circles joined by approximately 5 cm (2 inches) of fabric. The two circles should be about three times the size of your child's face. 5 cm (2 inches) from the edge of the cloth, cut a hole in one of the circles large enough to comfortably fit around your child's face.
Glue the two circles together using the hot glue gun and starting from the join in the fabric. Follow the edge of the fabric down to the level of the ear of the face hole on each side and then leave to dry. When dry, place the moon, like a hat, on the child's head with his face in the hole and test the fit; if necessary, glue the seams further down the sides of the costume.
Stuff the moon shape with cotton batting. This will fill out the shape of the moon and prevent it from going floppy.
Cut planets out of the felt. Use the different coloured felt to make different planets; for example you could cut a gold circle with a red ring for Saturn and small red circle for Mars.
Attach the felt planets to the T-shirt using the hot glue gun, leaving room for stars. If making the costume with your child you can increase the educational aspect of the costume by gluing on the planets in order of their distance from the sun; Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus, Neptune and then Pluto.
Attach rhinestones to the areas of the T-shirt not covered with planets using gem tack glue. These represent stars.
