Fairy Lights on Bedroom Walls Worth It?

I've been thinking about adding fairy lights to one of my bedroom walls to make the space feel a little warmer and more cozy. I see a lot of photos online and some setups look amazing, but I'm curious how they work in real life.

Do you have fairy lights on your bedroom wall? If so, how did you arrange them? Did you go with simple hanging strands, photos clipped to the lights, or some kind of pattern?

I'm also wondering about things like brightness, durability, and whether they get annoying after a while. Any brands or styles you would recommend or avoid?

Would love to hear what worked for you and maybe see some ideas from people who have already tried it.
