Moon phases. Looks to be old-style, not sure if it actually is old info, but fortunately for me, we've known most of what we need to know about the moon phases for several hundred years now. (Not, obviously, the mineral content, or many other vital facts about luna, until very recently... but none the less even if it were inaccurate old science is still interesting, even when not accurate.)
There’s something about looking at string lights that is very soothing and relaxing. Maybe it’s because of the low, twinkly light, maybe it’s because they give off an aura of coziness, or maybe it’s because they are often accompanied by lots of blankets and cute pillows and other aesthetically pleasing decorations – but whatever it is, string lights have a magical vibe to them that makes them the perfect piece of room decor.
