Yeah, you're right. Bevel edges would have looked funny disappearing behind the corner detail, and there was no way of having them trace around that odd shape.
I made another one. Smaller and more subtle than it's sister:
I didn't stain this one so dark, but otherwise the manufacture was much the same as the previous one.
Apologies for the poor photos. Lighting conditions were awful, with a window showing in the mirror and it being such a gloomy day. Here's the same mirror in its previous frame (the 1970's called and demanded it back):
I can't tell you about the first mirror, because the stain's original container leaked, so I transfered it to a big plastic container, and my writing on the outside subsequently faded. This latest one I used Colron "Georgian Medium Oak" wood dye, 2 coats of clear water based lacquer, and then because it was a little too red, a coat of Fiddes "Rugger Brown" wax.
