This is certainly one way. With a blank wall and zero ideas for how else to use it — yup, it's one way. This "solution" — ostensibly for TP roll storage and the so-called shuffle of shame — is rife with potential for an OCD attack if the rolls don't diminish at the same rate. We might go positively nuts when one of the rolls ran out.
The project is a post on Instructables, a kind of open forum for DIY show-and-tell. The comments are the best, ranging from absurd to surprisingly practical. The more practical suggestions include offering an assortment of thicknesses and textures, or labeling the holders for each member of the household, who are then individually responsible for their own consumption and replenishment.
Some observed that this would accommodate people with different arm lengths quite nicely. And still others conceived of a host of practical jokes, such as executing this project in a friend's bathroom while they're away, for a big surprise upon their return.
