The easiest way to make a mummy costume is to tie four or five strips of cloth together to form a bandage. Continue making multiple bandages until you have about 10. Then, put on a white base outfit and start wrapping one of the bandages around one of your legs. Work up from there, tying the bandages together as you go to help them stay up. When you get to your arms, wrap your hands first and work back towards your shoulder. Use any leftover bandages to cover your face.
