Feed backs nailed up (or inside a garbage can) work well for disposable garbage bags. Use clear tubs to store stuff rarely used, you can buy them fairly cheap at Target or Walmart. Little supplement tubs work well for storing knick nacks, I use mine for keeping extra leg straps and snaps for blankets. Also, if you are going on a trip and your horse's supplements tubs are really big, you can use an old plastic water-bottle for storing supplements. I used to use the water bottles for selenium supplements when I went away on a trip- handy when I only had a tiny under the manger tack room for everything except hay!
