*hires the engineers as personal knights*
My dad is just very bitter about everything and anything, and can only talk negatively. There's some head issues. Probably diagnosable ones, but I don't think that should give him a free pass to being a )&@@@$($&@
Would Paint/Paint.Net be ok for making the letterhead? They're all I've got at my disposal....
Yep, go with what you've got. "Good enough for government work," as they say. If that jerk (um, sorry to say that about your father, but he is) complains, burst into tears and say "But Daaad, that's the best I can dooooo..."
Or else point out that it cost him nothing but some snarling, which is a ton cheaper than a professional could do.
I actually don't think he'd notice if the letterhead is suboptimal.
(I have more thoughts on your father, but I'll take those offline. Meanwhile, have a hug, newly crowned Ruler of a Derelict Airport! Promotion ceremony will be held tomorrow.)
