The idea is to "hide" (from yourself) a few filters, a package of coffee, a roll of toilet paper, somewhere where it'll be logical to find it, but at the same time you shouldn't be able to see this stuff every day (since then you'll know you have it and you'll end up using this stash without creating a back-up plan). In the picture above, you can see a few coffee filters peaking out from a milk jug--they're almost next to my "regular stash" (far right).
Other items to consider for your secret stash: a ration or two of your dog's food (for your dog, obviously), some toothpaste, shampoo, and cotton pads for removing make-up.
Milk is probably the only item on this list that will make me put on shoes and go to the store (I love fresh milk in my morning cup of coffee too much).
Thank you for stopping by Pieliekamais!
