An apparatus for preparing material pieces to be sewn together includes a planer structure including a top surface, a bottom surface, a first end and a first and second edge. The first edge includes a first lip extending a first distance below the bottom surface where an edge of the material aligns with and touches the first lip and the material can be marked along the second edge. The second edge further includes a second lip extending the first distance below the bottom surface for holding the material to a flat surface. The first end is broadened and includes a third edge at an acute angle to the second edge. The third edge includes a third lip extending the first distance below the bottom surface where the material having the acute angle aligns with and touches the third lip and the dog ear of the material can be trimmed.
