DIY Cement Mushrooms: The crown is created by digging a hole in the ground and filling w/ cement, the stem is a two-liter drink bottle w/ top + bottom lopped off. Just in case I ever need a cement mushroom.
Just 3 simple steps: Pour quick-set concrete into the mold on any flat surface. Smooth with a trowel. Wait one minute, lift mold and move on. This mold measures 20 inches x 24 inches x 2 inches, and holds one 60 pound bag of premix concrete.
