First, you'll need a drill and this was the first ever drill project for me. My holes were uneven so measure very carefully and remember which side ends up where 😁 These look cute on the wall. They are small so folders can only fit one way. The tab gets stuck in the metal and you have to bend the folders to fit with the protruding tab. I'm going to look for folders w/o a protruding tab and that should solve the problem. Won't hold much but some. I got this for m home office and, again, love the look but it doesn't really do the trick I need it to.
