i'll tell you a solution i would use my self, if there are N members in your house, keep N*K bag for use, K is integer and K > 0 if you you want to save money, K = 1 note: there are bags that have mutiple places, to solve the problem of unidentified items do the following: - put a big bag for every member - at the regular time of cleaning - sort out duplications .. etc to identify items: - force family to make items unique, when similiar unique in color, if different, different in size - you can use tags, tag similar items .. etc i hope i helped, even if it's a littel
