Have you ever wanted to make a sun costume? Well now you can. This is a costume for Halloween that you will never forget.
Steps

Step 1. Choose a solid cardboard to make the costume
It should be large enough for your torso or the torso of the person who will be using it. It also has to be strong enough to wear (it shouldn't bend).

Step 2. Cut two circles that are wider than your torso
Draw the circles first, then use a utility knife on a safe surface to cut them out.

Step 3. Drill two holes in the top of each circle
Use a pencil or the end of a scissors to make them.

Step 4. Thread a string (or any sturdy string) through the holes you just made
Tie a knot at one end of the rope and leave the other hanging. Make sure to use a rope that is a good length (see next step).

Step 5. Tie both sides of the string to the other piece of cardboard, so that the pieces of cardboard are connected
Leave enough space in the middle for your body to fit: one of the circles will be on your back and the other will be in front. The string or rope will hang over your shoulders, so keep this in mind when measuring the final length.

Step 6. Create the rays of the sun
Use leftover pieces of cardboard to cut out shapes that look like stylized representations of the sun's rays.

Step 7. Glue or staple the rays around each circle
If you're using glue, let them dry before moving on to the next step.

Step 8. Paint each circle the color of the sun
Most will be yellow, but touches of orange and red for details are fine.

Step 9. If you want the sun to have a little more character, draw eyes and a smile in the front circle

Step 10. Let everything dry

Step 11. Dress in yellow clothes (or orange with red)

Step 12. Put your neck through the hole as if you were putting on a t-shirt
Now you are ready to hit the streets dressed like the sun.
