At my parents place we have an old rolling tool box that we put grooming supplies in one drawer, extra fencing tools in another, extra latigos and such in yet another, and so on so forth. For the saddles dad built a 6 saddle rack out of angle iron with bridle hooks on the end, then on the wall we have a bunch of hooks for halters and such. We keep grain in garbage cans. On the wall at the end of the alley is where we hang the harness.
Now that I am boarding, it really is hard to keep everything together! Using an old trunk for extra pads, bridles and such. A carry type tool box for grooming supplies, then hang my bridle on the saddle horn w/ pads on top of saddle. Also have a cloth grocery bag with medical stuff. The tool box and grocery bag sit ontop of trunk.
Definitely wish I had my old set up!! Lol
