Use the cereal box strips to make a ring around the top of your head, and then one running horizontally under your chin, leaving a little room around your head (remember, you have to wear it). Use the rest of the strips to fill it in solid, making sure you try it on a few times.
Once smooth enough, draw the outline of where you want the rough cuts for the mouth and visor. Use the dremel or cutting tool to cut them out, starting slightly smaller than you expect it to end up, incase you need to make changes.
Step 6: Step 6
Cut out and add the raised details with the craft foam gluing it together with the hot glue still. Add the first coat of paint to cover it all up. Once dry, use the dremel to cut it in half so that it will open later.
Step 7: Step 7
Add the hardware, so that it opens and hinges shut. Seal this around with the hot glue and then finish with coats of paint. Here you can add the detail paint to embellish the raised details.
Step 8: Step 8
Hot glue in the black screen mesh to make an easy and affordable visor that you can easily see out of. You can also glue in bits of craft foam for comfort. Now try it on. The costume however, that's up to you haha.
