We've been reading comments that suggest that some landlords limit the number of holes you can put in your walls. We've lived in plenty of rentals over the years and have never come across this particular injunction, but even so, as a matter of course we've always patched any holes we've made upon moving out. Having this basic skill in our back pockets has made us feel better about the many holes we always make in the process of moving in and getting settled: to hang art, shelving, wall clocks, and here in SF, to bolt tippy furniture to the wall for earthquake safety. That said, it occurred to us that a little hole-repairing tutorial would not be a bad thing for AT readers during Reversible Decor month. We searched the web for a good one, and lo and behold, found this one, which includes pictures and covers both plaster and gypsum board walls.
