I have a second bedroom home office/music studio that I’m putting together, and I’m looking into area rugs but not sure on the right size. The room is roughly 10x12 (a little larger) with a desk facing the wall and a storage bench in the corner (not pictured) for clients on occasion. The center of the room will be left open for use as a music studio. Looking for ideas on rug size or color, and mostly wondering if the rub should extend under the desk or into the doorway.
