Would you do a thread at some point explaining how you did them ?
I'd love to explain it in a step-by-step fashion, but it's difficult to put into words.
Those who use Photoshop know that it's all about using layers which are then superimposed on top of each other.
The Air Rhodesia decals were no exception and were made up of multiple layers which can be seen down the right hand side of the following screen-shot:

As far as the designs are concerned, it's basically all down to the ability to draw straight lines and getting the dimensions (and the colours) right. Not as hard as it sounds !
With regards to the dimensions, it usually starts off with a strip of windows. Cheatline dimensions can be gauged by comparing them to the windows, and then once you've got the cheatlines sorted out, you can gauge the dimensions of the doors by them. Doors are relatively simple to draw - four straight lines and a circle spilt into quarters.
Fonts are sometimes more difficult, but if you haven't got something similar to what you're looking for on your PC, you can sometimes find them on the Internet. As an example, the Boeing font was downloaded for free from some web-site, so with some manipulation, I managed to write BOEING720 in the right size and colour, and then add it to the cheatlines as an additional layer.
Another useful idea is to try and get a side-view of the aircraft that you're trying to model. The following pic was handy in trying to get the dimensions and positioning right, even though the resolution wasn't very high.

When it comes to side-views, I'm often surprised by what's out there in Internet land. I even managed to find port and starboard side-views on Airliners.net for a short-lived airline that's always been of interest to me, and they only ever had one DC-8 !
There was no excuse not to have a go. (Only about 100 excuses in the loft not to build it.....yet !)

The English font was available on the Photoshop software and coloured using the eye-dropper tool, while the Arabic font was picked off the photo using the magic wand tool.
I'd encourage you to have a crack at making your own decals. The satisfaction of making something unique is often greater than making the model itself, and if I can do it, anyone can. (Hell, everything I know about Photoshop is self-taught - I couldn't even read Photoishop for Dummies without subtitles !)
