OK.. I attempted this on my own, that was a mistake I know, I really do know now!
The stickers I was sent were weird, the one was set out in such a way I could put it on in one go, the other had the 'ST' and the back bit were up the wrong end (the stickers were in two parts so you don't need to cut at the door) so I had to cut this off to do it separately, that was on the passenger side.
Here's the passenger side:

There area few bumps which I'm not happy with, but from a foot away you can't notice so decided to carry on.
I though the driver side sticker would be easier given that I only had to measur the correct height once, but it collapsed in the middle with too much slack and could do nothing about it - attepted to pull it back, but the sticker stretched and wa then out of shape. This is what's left of the driver side!

I am leaving the passenger one on for now, in case I can get a spare, anyway you can only look at one side at a time

Now I am kidding I will not be leaving just the one side on indefinitely, we'll see what happens!
