There are not many similarities between Edwards and me, but one is there. Edwards would go out on horseback to think. While he was gone, he would jot notes on whatever paper he could find. These would then be attached inside his jacket.
I have no horse, but I do use a lot of paper. And I use will use about anything when thoughts come to mind: paper napkins, gas receipts, etc.
Above is an example from a couple of days ago. A gas receipt and a card from the gym were brought into service!
