What Should You Consider Before Choosing Wallpaper for Your Home?

Ok so I've been stuck on wallpaper for my living room for like three weeks now and finally realized my mistake — I kept picking designs I liked before checking how they'd actually work with my room. Big rookie error apparently. Held a sample up against my sofa last weekend and a pattern that looked amazing on my phone just clashed completely in person. Lesson learned. Also someone at a wallpaper shop gurgaon told me to just do a feature wall instead of covering the whole room if I'm not fully sure yet, way less commitment and way easier to change later if I hate it. Ended up checking world of wallpaper since a wallpaper shop near me search kept bringing them up, and seeing actual samples next to my furniture made this so much easier than endless scrolling. Anyone else pick the pretty design first and regret it later lol
