Here's an example of how to get a nice little customized tack room for a minimal cost.
I'm reorganizing my tack to make it more convenient to the front door, so I can conveniently transport it out to the barn (also see my other recent Instructable, http://www.instructables.com/id/Rolling-Saddle-Rack-Cart/
, for easy transport of tack from the house tack room to the barn). I've made a small tack room in an alcove by the front door, with tack racks and hooks for three horses and a saddle cart.
I want to hang several saddles, bridles, and miscellaneous in this area; I need saddle racks and bridle hooks. I want to put my barn shoes and riding shoes on the floor and have them out of the way (don't really need anything but a defined area that I won't trip over them as I go by). I want to stick a few things on a shelf so they're handy as I walk out the door, so I need a shelf.
Things are slightly complicated by the fact that the wall is rough-cut wood, and I don't want my tack getting scratched up by it, so I need something to protect my tack.
