I painted the porch assembly while it was still on the sheet, just like I did the windows and doors. I then punched it out and glued it to the dollhouse. I had to touch up all edges. I used stain on the railings and paint on the posts.
Though the porch assembly is small, it is remarkably easy to install. This is most likely do to the parts being so precisely cut by laser. The porch parts, like the windows and doors are paper thin wood veneer.
