This is how I made our Homemade Outer Space Family Halloween Costume. I got 3 large 36 inch balloons and paper mached them for the earth, moon and sun. I let them sit for a couple of days so that everything was dry.
For the moon, I added craters. I popped the balloons and painted each one. The kids helped me with the sun and moon but the earth was too tricky. I cut arm, head and leg holes in all three. I outlined the earth with puffy paint. I painted each one with glow in the dark paint. I hot glued miniature astronauts to the back of the moon. I used sticky back yellow felt for sun’s headband and cut yellow foam for the sun and glued it all around.
I bought the astronauts helmet and boots. My husband brought home a chemical suit from work and I used fabric paint for the NASA sign and flag. I was the shooting star. I just covered a cardboard star with tinfoil and hot glued stars all over my shirt. It was a blast making the costumes and we are already thinking for next year.
