Thank you very much @MiataPlay , @Sandraelle , @ZeeGee :)
@ZeeGee , Unfortunately I can't find the tutorial on TSR but I had saved the .pdf I used way, way back then so send me a PM if you want the file. It's titled "Wall Murals 101, A tutorial for The Sims Resource using TSR Workshop" by @Rennara .
The tutorial was created by @Rennara so I've linked
here to the wall downloads referenced in her tutorial. It doesn't seem I can message her on TSR without signing up, so maybe when things are not so busy I'll look into that to see if she still is active and can provide the tutorial link.
