It's funny that you should bring this up today. I was thinking just this morning that I might make a picture frame and maybe take some pictures and make another tutorial about "how I do it".
I have a jig that will clamp up the entire frame all at once using only one clamp! That and another way to add splines for strength on mitered frames (but the splines don't do much for "looks").
Guess I have a project for tomorrow!
