Where is the best place to choose wallpaper?

I'm redecorating my living room and decided to go with some cool wallpapers. I've been browsing online, but there are just so many options! Can't seem to settle on a particular style or design. Also, I'm not sure how many rolls I'll need for my walls. Any experts in here who can help me out with this wallpaper dilemma?

 

I recently redecorated my home office, and I had a fantastic experience with California Wallpaper. Their team was super helpful and friendly in assisting me with choosing the perfect design for my space. They asked about my preferences and even helped me visualize how it would look. As for your concern about terrazzo wallpaper peel and stick not sticking properly, I haven't had any issues with the ones I got from California Wallpaper. The quality seems top-notch, and the installation process was smooth.
