Barn doors a great. They take up little operating room since they don't need to swing open. They don't get blown open, or slam shut. Best of all they can bring a touch of character to any room.
With guests staying with us we have had to devise ways of creating privacy in an office/guest room. A dressing screen kind of worked(not really) but was awkward to use as a door. A curtain was just too flimsy and offers no audio interference. In other words, guests make noise, like snoring and the sort. It is also nice to be able to keep the cats and their curiosity out of the room and off the guests. So the installation of a solid door was in order.
I did this in kindergarten.
OK I need to be less bitter. The use of strong magnets, iron filings, and resin is great and produces wonderful "flowers" that ultimately display the wonder of Mother Natures magnetic power. The ultimate issue that I take is, why a stool? A stool is about one step up from a lamp, which -by the way- can be made out of anything. For an object that is as heralded as this I expect more, much much more.
Barn door rails and wheels come in many variations. Here they are applied to an exterior window, quite brilliantly I might add. These wonderful workhorses (no pun intended) have lasted decades and centuries and I can't wait to use them on a project.
