these are most of the steps to do this costume, i didnt get pics of the backpack rig inside. but is a simple concept enjoy i hope you like it!
Step 1: Pac Man Costume
first we cut out 2 sides out of 4x8 cardboard, and cut a strip 2 feet wide and taped it in between both sides with durable duct tape. cut a hole in the bottom big enough to get inside and enough room for legs to move while walking. this costume is 4ft x 4ft
Step 2: Painting
We applied yellow duct tape over original silver tape, and painted the entire thing with yellow acrylic craft paint
painted the eyes and added spandex material inside for the mouth (2 pieces) taped and stapled on the inside to hold it well, and staples and tape stay hidden. is a hidden hole between fabric in the middle to reach a hand out if necessary.
put a small hole in the mouth with a box taped beneath it to catch candy , and small flap that opens inside to take out the candy. inside i didn't get pics but i used a thicker cardboard inside as a flat backing and ran backpack straps through 4 holes in it so it can be harnassed .placement depends on the size of the person. this costume is 4ft x 4ft. and very noticeable Added yellow duct tape on the top for extra rain protection and durability.
