The SFG concept of compost making involves mixing different types of plant-based materials, chopping everything up into small pieces first, keeping the pile moist, and regularly moving or turning the pile. I've made my frame out of chicken wire and put it on ground-cover material. The idea is that a few times a week, I'll put down the second square of the ground cover, remove the frame from the pile and put it onto the second ground cover square, and move the compost pile into the frame again, mixing it up as I go. The chicken wire will also allow air into the pile - hopefully creating better compost and not a slimy sludge...
Since I took this photo I have covered the top of the pile with one of the squares of ground cover material, so as to prevent the pile from getting overly wet from rain..
