I have a couple of ways, depending on my glass & size circle (I'm really thrifty with glass). I'll try to draw a diagram & take a picture of it.
They are not perfect, have a few bits I have to grind off if I'm not putting the glass in a full fuse. If I am, they are good enough for me, because the glass pulls in pretty good. Of course, I also have 2 layers, so that wouldn't really do the same for you
I don't know if you can see well enough, but there are a few places that aren't perfect. But being that they are up in my skylight, they work OK, but it's a layer of clear fused to a layer of color with a steel loop between.
I'll have to go do one with some scrap & see if I can take pictures or something.
