Concrete Cloth - A flexible fabric impregnated with a special pre-mixed cement that hardens when it’s hydrated. So not only does it make creating irregularly shaped items out of concrete a lot easier, like say shelters, ditches, retaining walls, pond linings and chairs, but unlike a regular concrete mix you can’t use too much water, so it’s idiot-proof as well.
Water-soaked soil is the worst enemy of retaining walls because it exerts enormous pressure behind the wall. Adding good drainage behind block or stone walls is crucial for long-lasting, bulge-free walls. Start by laying perforated plastic drainage tubing along the base of the wall slightly above ground level so it can drain to daylight. Slope the tubing about 1/4 in. per foot.
Wine cork spools-use for ribbons, trims, scraps of long fabric.
