An adjustable form holder, comprising a first bracket and a second bracket pivotally attached to each other by a hinge, so as to allow relative pivoting about a substantially vertical axis. The first and second brackets provide substantially vertical slots configured to receive an end of an elongate concrete form member. The hinge allows the concrete form members to be held in place on-edge at a selected horizontal angle relative to each other. The hinge may include a central aperture for receiving a form stake. Multiple form holders may be stacked for forming walls.
