Living room curtains help

Sariah

Hello. So I’m unsure if this is right place to ask this. But seemed like the best place. Idk. But I’m decorating my living room and I have 2 windows right next to each other and I wanna put curtains up. But idk what would be the best way. 2 curtains or 3 with one between the windows. Here’s a pic of my windows. Please help!
