I stained a lot of interior trim, making sure to paint or stain every side so no raw wood is visible from any angle. Once the trim was installed, I put up the curtains. After hanging the curtains, I hot-glued small flowers to the corners, using long tweezers to reach each window.
To cover the gables peeking through from the second floor, I first painted them white and then glued lace trim over them. This is an easy way to hide those overhanging gables, but you can also use other methods like wallpapering or trimming with wood strips. It's important to conceal them since they aren't visually appealing.
I made a paper template for the window seats in both bays by creasing the paper around each seat. Since both seats are the same size, I then cut out a template from thin cardboard and upholstered it. I always use hot melt glue for upholstery because it holds quickly, preventing the fabric from shifting. I used cotton balls for batting and chose a neutral fabric that matches the curtains. I added lace trim to the front edge and glued the finished cushion to the window seats. I also added trim to the steps to cover the wallpaper on the top riser using simple basswood strips. Additionally, I trimmed the edge of the higher floor in the attic with more basswood strips.
