Here is an example of two styles of letters for kids rooms. The large white “R” is laser cut MDF that is then spray painted whatever color you want and then attached to the wall using double sided tape. The other letters are also MDF but we cut them using a Doctor Seuss font and then laser cut some fun fabrics as well. We painted the MDF with acrylic hobby paint and then used Modge Podge to attach the fabric to the letters. They were then attached to the wall using double sided tape.
