With all my experimenting with concrete and what can be done with it, one of my favorites is the garden markers or signs I make using new concrete forms or, using old, broken chunks of concrete than can be found when a sidewalk or patio is torn up, for example. I think the forms made are very attractive additions to the garden, patio, walkways, or anyplace your imagination can take you.
Step 1: First Find Some Concrete Pieces
These pieces are from a neighbors torn up sidewalk. This is just one of many substrates I use. Others include bricks, rocks, cast pieces of concrete, tiles,and so on.
