Cut your logs into at least quarter logs with an axe or log splitter. The bark around the log will prevent it from drying completely and also harbors insects that could ruin the wood. Cutting them into quarters allows for airflow to the core of the log.
Clear an area in your storage shed, or lay a wooden pallet onto a flat area of ground outside.
Stack your logs into a pile. Stack the first row, then change the log direction for the next row. Change log direction for each row to allow for as much air circulation between logs as possible.
Cover wood, if you placed it outside, with a vinyl tarp. Cover only the top of the wood pile, like an awning, to encourage air flow under the tarp.
Allow wood to dry, or "season" thoroughly this way, before using it. You can tell that the wood is dry by picking up one of the logs. If the log is lighter than it was before, it has dried. Oak takes about 2 years, Pine wood, and the wood from fruit trees, can be used within only a few months. Beech wood can be used in about a year.
