Do you have a rusted-out wheelbarrow waiting to be hauled to the dump? If you've been homesteading for at least a decade, I'll bet you do.
Well don't haul off that wheelbarrow! Prop it up on cinder blocks and turn it into a fire circle.
I ran into this fire circle at a friend's house yesterday evening and was highly impressed. Its owner told me the wheelbarrow not only contains the fire, it raises the flames up for easier management. During the winter, she finds it especially nice to have the heat closer to body level. Sounds like a win/win!
