How to make your own duct tape dummy!
Step 1: get a trash bag. Cut arm holes and a head hole. Put it on.
Step 2: Get rolls of duct tape. I used two, but for bigger people? maybe 3 or 4.
Step 3: Get a friend. Have them cover you up in tape. You need at least 2 layers thick of it. This will take a while. Mine took about 3 hours.
Step 4: Get out. Once you've covered it pretty good, have your friend cut you out from the back (up the spine). Take it off
Step 5: Close it and stuff it. With newspaper. It's cheap, so you might as well use it. Then close up the arm, neck and bottom holes so the paper doesn't fall out. Voila! It's done!
Not only is this handy for mounting your armor, but it can be also used to help with other, fabric costumes. ^w^ I'll definitely use it for pattern making for dresses and cosplays in the future! I've been meaning to make one for years, and now I finally did!
