Thanks su_g, yes the sleeves are scaled incorrectly. I have to get the hang of the cage deform in GIMP as that seems like the only tool in there which might do the job. So far I am not getting what I want from it, hopefully I'll find a tutorial which will help.
Thanks, was just about to leave you a note letting you know I had done an update. I also checked the wallpaper option and it looks like it would be great as far as I can tell (We don't use wallpaper here much).
