Well, back to good things. I took plywood, several minutes with scroll saw, and my dollhouse will have these... corbels, right. I've found this design in Russian carving-something album, something tells me it's not the last time I'm using it.
It's far from perfect, I painted it with acrylic, and sandpapered - it looks a bit worn now. I think it should be more realistic.
Now I have to do only balcony railings and the door, and it'll be done.
