Pillow cover without a pillow. I rolled towels and put them in the pillow cover. It’s not perfect, but it works for now.
Window Valance. I have no sewing skills and couldn’t find a valance that I liked. I did find a kitchen towel at Crate & Barrel that I thought would work. No sewing was necessary. I just draped the towel over the rod. I might velcro the insides together, but maybe not.
An empty corner. I took the homemade bench we made for the end of the bed and stood it upright adding books and plants, etc.
And a couple of more common hacks: the throw over the chair is actually a blanket scarf and the plant on the table is in a spaghetti jar.
