I'm checking the listings I find to see if I get lucky.

Thanks! But is that just for Canada? I'm in California. I'll look around on our versions, though. It's a pretty big frame, though, so I think I'd have to get pretty lucky.

Well, I'm getting whiplash from changing my mind. It's a good point. I'll have to keep thinking about it.

This would be a first for me, but I'll spend some time learning, first.

Fair enough ... doesn't exist as far as my wallet is concerned.

I'll take a look -- not luck at the first couple but I can ask around.

I'll watch some YouTube and figure it out!

I have a TAP Plastics nearish that I think can produce anything I want -- but it doesn't look cheap.

I'm not sure we've got a glass/mirror shop here -- that doesn't ring any bells, although I haven't tried buying glass much before. Searching online doesn't find me much.

But even at Lowe's, glass is clearly cheaper than TAP. I might adjust my plans to match the 30x36 size they sell. I'll just have to learn some new stuff about putting it in. Since I'm building the frame from scratch, all the "How To Install" videos don't help me much. Could I use a dado for this? I might need to make something closer to a traditional window frame (which is a lot more work, of course).

Huh, would not expect that; I'll go price some before I commit.

Yeah, I'll sketch it out and maybe try that, thanks.

How would you build the cross? Make each line two pieces, one on either side of the plexi? I like the idea of being dismantle-able, but I think it would add to the price tag. Trim is kind of crazy expensive these days.

Thanks! I don't even really have a baseline for thinking about the dado depth, so that's good to hear.

But the other comment reminded me about real/nominal size, so I might as well go a bit thicker.

Great point; I can't believe I forgot 1x1 doesn't exist. So 2x2 starts to make more sense.
