Choose a color scheme for the polka-dot room. You may use subtle pastels for a nursery to promote relaxation or bright, bold polka dots for a teen's room. Use just one color of polka dots or several different ones to contrast the style of the room.
Choose a style of polka-dot decor based on your child's personal tastes. This includes how many polka-dots will be in the bedroom, what size they will be and how you will display them. For instance, you can have a colorful kid's room using polka dots on the bed, floors and walls. You can also incorporate the polka-dot theme into other themes such as a classic red, blue and yellow room with not only dots, but stripes and shapes as well.
Decorate the walls with polka dots by displaying wall decals or wall hangings in the polka-dot theme. These come in a variety of colors and sizes. To do the dots yourself for a custom look, purchase stencils and paint to create a polka-dot wall according to your preferences.
Choose a polka-dot bedding set that coordinates with the color and style of the room. You may find a comforter covered in multi-colored dots or that has the polka dots in a specific pattern, such as arranged to make a heart or a star.
Continue with the polka-dot themed room by choosing area rugs that have polka-dots following the room's color scheme. To avoid overdoing it, choose one rug with polka dots and one or two other rugs with solid colors that match the room.
Decorate the kids' bathroom in polka dots with counter accessories, bath towels, shower curtains, rugs and other items.
