You can see one here: Walkmaker™ Stone Mold We've got a bird feeder on pole stuck in the ground and my wife is thinking this would be handy create a stone border for it to cut down on the seeds germinating there. Anyone used these things? Do you like them? I supposed the resultant bricks should be placed on a bed of sand? This particular mold doesn't look like it would be handy creating a circular pattern. I notice that Lowes has crack-resistance concrete mix. It has "special fibers" to reduce drying and cracking. It costs a couple bucks more a bag than the regular.
