I covered a piece of MDF to make a pressing board, and i covered it with a towel and then W&N batting to keep heat and steam from warping the board. Someone here made a new cover for her ironing board and used actual ironing board cover fabric she got at Joann's. Mine is topped with regular cotton fabric.
My new quilting room is under construction, and I'm excited to have a really big ironing station - good luck!
