dashed lines project

via work/space, via Touch, we find a "taxonomy of dashed lines" that prompts me to recall my own little invention (maybe someone's done it already; i don't know).

i like the way you enter a nice, fresh hotel room and see that triangular-origami move the housekeepers have made on the toilet paper roll. when i have guests, i do the same in the guest bathroom. i try to do it just for us (and use the roll that's under the sink so as to avoid making the origami move every time someone uses the toilet; rarely does my husband get what i'm going for, however, and so i have to redo my taper more often than i'd like).

so i was thinking that i could create a toilet paper roll that had a "built in" triangular shaped edge. here, in the image, above, the dashed lines represent the "tear spot," which is to be used for creating that lovely tapered effect.

apparently, there is a little invention already out there, the meruboa, which claims that "just pulling a lever makes the head of toilet paper triangle."

i'm not alone. there are a lot of people who like this little move.

i still like my idea. there is, however, the issue of keeping the edge from looking cheap and serrated, but i imagine that i might find a sophisticated paper-maker who can finesse the job.
