Mark master mason apron

The ordinary member's apron is composed of white kid leather with a triangular flap, bordered with a two-inch ribbon of light blue with crimson edges, and adorned with rosettes following the same color scheme, as recorded by Mark Masons' Hall. For Masters and Past Masters, these rosettes are replaced on the apron with silver levels, Mark Masons' Hall notes.
