In the wise words of notable Westerosi meteorologist Ned Stark, "Winter is coming." If you're planning to store firewood for the long haul, this graphic teaches you how to do it right.
As this chart from the Art of Manliness points out, just putting firewood in a haphazard pile can cause you some problems down the road. You want your firewood to be able to dry while it's stacked, so it's optimal for burning. Build your stack perpendicular to the wind so it dries faster. The chart also shows how to build wood towers on each end in order to stabilise large stacks.
