Alright, well, so much for that.
After spending nearly two hours today driving around trying to find a piece of presentation board big enough for the Roundel, I finally found one, got it home, spray mounted it, and started painfully exacto-ing it out. And then I ruined it. Trimmed the edges too messy with the exacto, which already had me pissed off, and then when I was finally done I noticed there was an air bubble trapped under the paper. So I did what any normal person would do: I got pissed and destroyed the whole thing. Ah, nothing like $50 down the drain.
I'll try again in a couple days.
