First find a big piece of cardboard.
Draw out an outline and then cut him out. I used an exacto kniife but scissors will also work. Kids ask your parents to help with this step.
Time to paint. Lay out newspapers so you don't make a big mess. You can get inexpensive paints at most craft stores. You will need tan, brown, black and white. I started with a white coat and then tan over that.
Use the brown to paint a crust on one side, black for the eyes and mouth and white to fill in the eyes. Before painting the eyes draw them on with pencil so you know where you want to paint.
You need to attach a string on the back so you can wear the costume. I took a second piece of cardboard and punched some holes in it to tie the string through. I then glued this on the back and tied off the string to adjust it for the correct height.
Cut a think slit right at the level of your eyes so that you can see out when you go trick or treating.
Now you just have to wait until Halloween.
