Wallcovering Installation – DIY or Professional Help?

I’m thinking about updating my home with a stylish wallcovering installation, but I’m unsure whether to do it myself or hire a professional. I have some experience with wallpaper, but I’ve heard that wallcoverings can be trickier, especially textured ones. Has anyone here attempted it themselves? Was it easy, or would you recommend professional installation for a flawless finish?
