Rows of spark plugs with names. Fun symbolism with the idea of a "spark" of knowledge as well. Similar to specimens wall. Spark Plug could be out parallel to wall instead of perpendicular. Variety of Spark Plugs mixed in as well.
DIY cute fabric to cover worn-out, faded, or melted standard fabric in your car. LOVE THIS IDEA.. wonder if my all brown interior would accept a bold leopard print.. or maybe a cool retro print that would not be brown but compliment brown.
