So for what it's worth, I'm going to call it finished...
Although I have glass already cut for my other six projects, and used it on this one, I may not use it with all of them since the reflections are a distraction and it really doesn't do the cutting any justice. I think miter joints on frames have their place on certain subject matter but I really like the look of butt joints more.
Though the more I look at it I think the 2 inch frame width makes it look chunky, maybe 1 inch instead??
Let the experimenting begin!
