Made the shadow box as a gift. It is for a memorial flag and the display. It is made of red oak. I cut down a 1"x 6" to rough width then used the cut off and with a locking miter joint attached it to the front to give the me e lip to hold the glass. I then used a couple different router bits to create the front profile. The back is simply a piece of lauan that has been flocked with a black felt. I am just waiting for the glass to finish it.
