Can anyone tell me wher to find handcrafted arrowhed shaped frames or shadow boxes?

The frame appears to be cut (in an arrowhead pattern) from plywood, is stained, and has criss cross etching along the edge of the frame. I saw one of these frames at an artifact show but no one can tell me where to find them or who made them.|||I could construct them for you if interested. Some of my work can be seen at wegnerwoodworkings.com. Contact info is available at the web site. Would need a more detailed description with dimensions to get started if interested of course.
