Here's some progress from the last day or so...
Inside, the floors have been worked on a bit more and the walls have been given a thin layer of messy plaster. The walls will probably have stains and potion splatter eventually. At this point I start shoving things inside to see if they fit and to wrap my head around what will be going where and to generate ideas.
I covered the exterior of the house in a layer of sewing paper tissue. I really like the look that it gives... a sort of wrinkly, crinkly skin.
It's coming along quite spookily!
