This is the window in my powder room. I would like to find or build a set of shelves, only a few inches wide, to fit inside the window and decorate with succulents. The southern-facing window gets a good amount of sun so it would be perfect. I’ve searched high and low for shelves or a rack like I am describing, even tried looking for spice rack that would fit, but I haven’t found anything perfect. I wouldn’t even know how to go about building something like this, like how to find the right size and thickness of wood. Can anyone help a clueless person with some pointers?
