For example, paint your walls a baby pink color that will go with all-white furniture. Pastel yellows and greens go well together, or you could choose a color scheme of pastel pink, blue, and purple.

Other print options include hearts, cupcakes, or clouds.

For example, if your theme is Hello Kitty, you can choose a color scheme of pink and white and look for things like lamps, rugs, or pillows that have Hello Kitty on them. Other themes could be unicorns, Pokemon, or Sailor Moon.

Pick out a pastel yellow for your walls, or an off-white color. Consider painting one wall a pastel pink, and another wall a different color like pastel purple or cream.

Pick out a Hello Kitty wallpaper border for your room, or look for wallpaper that has kawaii foods on it to cover an entire wall.

Select a duvet covered in watercolor daisies, or opt for a white bedspread with pastel-colored pillows for a pop of color. A ruffled bedskirt is another great way to make your bed look even cuter and more put-together.

For example, if you have a duvet with a rainbow on it, you might select pillows in the shape of clouds or that have a rainbow print. If your duvet has a yellow, orange, and pink floral print on it, you might opt for choosing solid-colored pillows in one of those three colors.

Pick out a dresser, desk, and nightstand that are all in white for a light, airy feel. Paint each piece of furniture a light purple to go with a room with purple accents.

For example, pick out a plush pastel green chair to go with a room full of pastel florals. Cover your full-length mirror in heart stickers to go with a heart-themed room.

Hang up a poster of anime or your favorite band. Make sure the method you’re using to hang the posters is safe for the wall in case you need to remove them later on.

Arrange the postcards or letters in a shape, such as a heart. Use tape, thumbtacks, or small wall adhesives to attach the postcards or letters. Consider using a piece of thick string and clothespins to display your postcards or letters as well.

Hang a pastel-colored painting on your wall to tie the room together. Create a wall full of art that you’ve done or collected from one of your favorite artists. Visit a craft or hardware store to find safe options for hanging things on the walls without using nails.

For example, frame polaroid pictures of your friends to hang above your bed. Write or print out inspirational quotes and hang them in frames around the room. White frames are a great option as they go with anything.

Place the plant on a windowsill if it needs constant light, or on your desk or nightstand for more occasional light. Make sure you read instructions for how to care for your plant, such as how often to water it, what kind of soil it needs, and how much light it should get each day.

If you have large plushies, place them on your bed as if they were pillows. Set smaller plushies on a nightstand, desk, or windowsill.

You can choose battery-powered fairy lights for easy use, or opt for lights that you plug in to an outlet. Some fairy lights even come in different colors or themes, such as butterflies, hearts, or flowers.

For example, outline a mirror with cupcake stickers or place Hello Kitty stickers on the handles of drawers.
