Thanks! I'm a real perfectionist when it comes to stuff like this, so I should be happy it wasn't a disaster...
I should be able to pull the creases out - when I was manhandling it and trying to position it, it stuck down and I needed to pull it away, so the suede has released a little from the door card, meaning it's more wrinkly. I think I can either spray it again underneath or maybe get some of the stuff you can paint on in the hope it'll be easier to control it. I need to go round the edges and stick it down anyway, so maybe some a-clamps will
help there.
All in all though, it's definitely doable. It's a pain getting the old foam off and getting the insert out of the door card, but as long as the glue holds in the armrest bit for a few years, I'll be OK.
It helps that the company I bought it from seems to have sent me much more than I ordered, so if I make a mistake it's a little less of a disaster.
