For the interior, I just used simple water based furniture paint, add to it some water too to make it thinner. Really good and easy and no bad smill or hard paint to remove. Washes with water before it’s fully dried. (Rust-oleum)
Just cut and use any plastic sheet from boxes. For example, toy box display the toy, peel off the plastic front and cut as you wish and to make a corner just fold it hard and voala you have it. ☺️ let me know if you manage and happy to help more if not, can make a video about it if needed
