To make a simple potting bench, recycle a picnic set by stacking the benches on top of the table, and add old fence boards on the side for support. Add hooks and paint if desired. Alternatively, convert an old sewing table into a potting bench by adding a small sink where the machine used to sit.
To make a simple potting bench, recycle a picnic set by setting the table on boards to get it to a good working height, and then stack the benches on top to create shelves. To allow for plenty of working space, stack the benches at the back of the table. To secure the benches, use fence boards on the sides, attached with two deck screws each into the sides of the benches and the sides of the tabletop. Screw hooks into the side to store hand tools.
Another option for a simple potting bench is a recycled sewing table. Paint the table with an oil-based exterior house paint for protection, and let it dry. Add a small, plastic sink in place of the sewing machine, and add a mesh sink strainer to the sink. Fold down the sides to create a work space. Remove the sink, and fold the top down to store.
