  1. Wash and dry sweatpants, T-shirt, and white fabric; do not use fabric softener.
  2. Draw a mask on white craft foam, and cut out. Be sure eye holes are large enough for child to see out. Outline and decorate mask with dimensional paint. Let dry 12 hours. Punch holes in either side of mask, and tie elastic cord in holes.
  3. Use dimensional paint to draw squiggles on yellow foam. Let dry 12 hours. When dry, cut out around squiggles, creating different geometric shapes.
  4. Paint foam balls blue; let dry. Use dimensional paint to make squiggles on balls. Let dry 12 hours.
  5. Following manufacturer's directions, fuse webbing to back of white fabric. Draw four oval shapes on fabric, and cut out. Fuse fabric to sweatpants, one oval on thigh and one on shin of each leg. Use dimensional paint to draw squiggles and dots on fabric. Let dry 12 hours.
  6. Use box cutter to remove bottom of box. Cut holes for neck and arms. Cover box with foil using clear tape and hot glue. Use blow pens to add swirls of color to front of box. Use double-sided tape to attach foam shapes to the box front. (Save a few smaller shapes for the helmet.)
  7. Cut two pieces of vinyl duct the length of child's arms. Fold plastic to inside, and cover with clear tape. Use clear tape to attach duct to ends of T-shirt sleeves. Stretch duct to full length, and use blow pens to decorate.
  8. Cut milk jug below handle, about 31/2 inches up from the base of the jug, and continue cutting around jug. Bottom of jug will be the helmet. Cut slits at corners if jug is too small to fit child's head. Use blow pens to color the helmet.
  9. Coil 14-gauge wire around the 1-inch dowel to make 3 inches of coil with 1 inch of straight wire at each end. Make as many coils as you'd like. Wrap double-sided tape to an end of a wire, and stick the end into a foam ball. Make three. Poke holes in the milk jug with a needle. Push the ends of the wire coils through the hole, and use pliers to bend wires flat against the carton. Cover wire ends with duct tape. Use double-sided tape to attach foam shapes to helmet.
  10. Coil 20-gauge wire around 5/16-inch dowel, and attach foam circles to an end using yellow electrical tape. Attach coils to helmet as in step 9. Hot glue batting to inside of helmet to protect child's head.
  11. Use foil to create moon boots. Cut a large piece of foil, and wrap around boot, taping in back to hold foil in place. Repeat for other leg.

With your alien being fully outfitted, send him from the mother ship to acquire candy in a target-rich environment. Or, if you've got a whole slew of space fanatics, create an alien force, then continue to the next page to blast off a couple of astronaut costumes -- even one for the family dog.
