ABSTRACT:
A method and apparatus for positioning matting for picture frames and the like under an oval cutter so that ovals or other configurations can be cut in the matting about the perimeter of circles of varying diameter. The positioning template comprises a first plate which slides on the base of the oval cutter and a second plate which rotates on the first plate. Holes in the first and second plates align so that an indexing peg stops rotation of the second plate at various preselected equiangular positions.
