My collection of quirky mugs is outgrowing the kitchen cabinet

I started collecting quirky mugs about two years ago, mostly from thrift shops and little local markets. It’s become this fun little hobby, but now I have around 40 unique mugs and my usual cabinet is bursting at the seams. I tried stacking them, but that always feels risky and I’m scared of chipping my favorites. I also thought about using a small bookshelf in the dining area, but it doesn’t quite fit the vibe I want for displaying them. Ideally, I want a solution that keeps them accessible for daily use but also shows off the collection a bit. Has anyone else dealt with a mug overflow situation? What’s your go-to storage or display hack that can handle a growing collection without turning the kitchen into a clutter zone?
