You should check out the cloth diaper pages at www.incontinencesupport.org. You will find that the recommended method of pinning a cloth diaper on an adult is the four pin method, which is similar to the four tapes found on most disposables. The problem is that an older child or an adult has different body proportions than babies. One tape on each side is fine for a short pudgy person, but doesn't work very well for a tall thinner one. The extra pins or tapes provides more support around the upper thighs which helps prevent sagging when wet. I wear cloth diapers at night and always use four pins. When I get up in the morning I can walk around unitl I can remove the diaper without it falling off.
