Mix quickrete cement in a container and dip a towel in it. Place the towel over a surface to form the shape like an upside down bucket. I put plastic wrap on the bucket to make easy removal once the concrete has hardened. Let the cement harden over night and remove it off the bucket. Turn it over and you have your planter. It will be heavy if the towel is large and thick. It will be lighter if the towel is smaller and thin. Paint the cement and seal it with a sealant spray. You can make different shapes by using large bowls or small planters you no longer use, etc. I always cover them with grocery plastic bags or something to be able to remove them. Be sure the concrete is smooth over the plastic so you are not left with pulling the plastic out of curves in the set cement when you remove it off the bucket. I hope this helps Lawanna.
Dip the towel into mortar mix that's a littler soupier than what you'd use to set a sidewalk. Dirape the towel over a bowl or bucket to dry.
