I rotate sets over time and sometimes add new display space. I added 4 extra shelves just last week, which will allow me to display another 15 or so sets. Some can also go on the wall, which helps a ton, as there is more wall space left than shelf-space. So, for 2024 I am OK. Next year will be a year of many decisions though. Which sets I take apart, and which I keep on display for another year.
