Take a large trash bag cut leg holes into it step into the bag do a dry fit cut off the excess from the top leaving right below your belly button mark a f in the front this way you cannot make a mistake. Then take paper towels fold them flat and make sure you have enough to use as absorbent material maybe 1-2 inch thick place in the bag and tape the papertowels to the bag ensure its securely taped then if you want add in booster pads where needed if male in front if female between the crotch. then slide up your newly made diaper make sure not to be forceful that plastic will tear once its up and fits okay get a pair of underwear and put them on to secure it while you get a very long piece of duct tape or packing tape and use the tape to secure the top of the bag(diaper) to your waist/stomach and you just made yourself a diaper note it will be VERY NOISY !!!
