Both staircases have been finished and installed. They are somewhat unusual and lack the detail typical of most die-cut staircases. The risers are quite tall, and the sides are rather plain. If you want to replace them with pre-assembled staircases, you should be able to do so, but make sure to take careful measurements before purchasing any expensive options. Die-cut dollhouses have specific custom measurements, which can complicate the purchase of pre-assembled components designed for 3/8" cabinet-grade dollhouse models. If you choose this route, you may need to adjust the openings.
Now that the staircases are in place, I've started working on the wood flooring. The shelf paper on the staircases blends nicely with the flooring. I painted the floors brown before applying the vinyl planks. A few things to keep in mind - the first floor has an edge that extends from where the floor begins. This edge is where the front panels will rest when closed, so flooring cannot be applied here. If this edge is too thick, it will prevent the front panels from closing properly. You can either paint the edge to match your flooring or use shelf paper like mine. I plan to use shelf paper later, as it will match better than paint.
When working with wood-look vinyl flooring, remember to stagger your joints. Avoid applying the flooring in one continuous piece; doing so will make it look less like miniature flooring and more like a single slab of real wood. This flooring is easy to work with, but some planks may be narrower than others, typically found at both ends of the sheet. Don’t discard these narrower planks; they can be very useful for fitting at the ends of a room where a smaller plank is needed for a good fit.
