One of the best ways to decorate a child's room is to decorate with a theme or color palette in mind. Here are some tips for decorating a child's room thematically, whether it's for a girl or a boy.

1. Look at your child's favorite books, magazines, and even the internet for inspiration on a theme.

2. If you have multiple children, you should involve the older child in the project to find new ideas, choose their favorite colors or sports, and artistic interests or characters from books or movies they like.

3. Buy materials, wallpaper, or paper to reinforce the chosen theme. Choose a main print that will set the tone for the entire room.

4. Choose a background color that you use for walls, ceiling, and floor, guided by the chosen print.

5. Choose a focal point for the room. Most emphasize the bed, but you can also emphasize a shelf or a painted wall, a decorated play area. The focal point should reinforce the same theme chosen.

6. Be creative when selecting decorative elements. If they like tennis, tie a net to the head of the bed and arrange tennis rackets (preferably bought second-hand to be as cheap as possible) around it, use tennis balls in all sorts of combinations.

7. Use sheets that match the color scheme and theme chosen.
