Keep your firewood dry by creating a Grip Clip wood cover. This is simply a blue tarp with some Grip Clips attached to it. The cover pictured below is folded to the desired size, held in shape with Grip Clips, and then staked to keep the wind from blowing it away.
You can easily increase the size of the wood covering by creating a lean-to. Position the wood pile next to a fence. Make the lean-to by attaching the tarp to the top of the fence: Fasten 2 or 3 Grip Clips to the upper edge of the tarp and attach the Grip Clips, via cord, to nails or eyebolts in the fence. Use a 2x4 as both an anchor and a spreader for the tarp: Attach 2 or 3 Grip Clips along the bottom edge of the tarp. Then fasten the Grip Clips, via cord, to 2 or 3 nails or eyebolts (or holes drilled) in the 2x4.
