Please bear in mind that when we made this costume, we wanted a stainless steel-looking RDA. That added quite a few steps to the process, as we used aluminum foil to match the color. If you use plain black or colored poster board, you can follow along but avoid at least 50% of the work. In retrospect, we highly recommend avoiding the aluminum foil if you want to save time and a stainless steel look is not a necessity.

What you’ll need:

Heavy Duty Aluminum Foil – $8-$14 per roll (or free – you might have some around the kitchen already!) If you decide that using aluminum foil is too much of a hassle, feel free to use black/color poster boards as an easy substitute – these should run you a couple of dollars each at an office/craft supply store. You’ll need about 4 in total depending on the size of your headpiece. Original Gorilla Glue – Around $7.00, or just use any strong adhesive glue Transparent Tape – $3.00 – $4.00 per roll Some cardboard – Free if you have packing boxes laying around the house Tape measurer / ruler – Free or $3-4 A few wire clothing hangers you’re willing to destroy or some skewer sticks – Free or $3-4 for a large pack of skewers Aviation snips (if you’ll be using wire hangers) – $8.00 (or free if you already have some on hand) Some 8 1/2 x 11 inch printer paper to make your template A large, round bowl or plate from your kitchen A cup, bottle, or anything round to trace Some binder clips to use as “clamps” – $4.00 for a bunch or use anything that can clamp and hold together some cardboard while glue dries

Total cost = a maximum of $30.00 if you purchase all of the materials on Amazon at full retail price…

However we were able to pull this entire project off for free since we had everything lying around the house already – you’ll probably find that you have most of these things as well.
