I recently got a tbr cart and I am also in LOVE. I also sort in ✨vibes✨ things I want to read most/the next book in series I’m reading on top shelf, second shelf is mostly books in series I’m not up to yet and bottom shelf is stuff I will read some day but I’m definitely not in a rush for. It also really helps me with my book collection system. Book come off the cart to be read and then only make it onto the book case if I actually enjoyed the book. I have a big wooden book case that I am dreading the day it fills up 😥
