Setting up and decorating the classroom for a children's birthday party in kindergarten is a fun and creative activity. Biodegradable paper sticks can play a great role. They can be used not only for food but also for decoration. Adds more fun and personalization. Here are some ideas for decorating paper sticks:

1. Colorful Lollipop Packaging: Plug the paper stick into gummy candies of various colors and shapes, and you can get a lollipop. Use colorful wrapping paper or tissue paper to wrap the lollipop paper sticks. Cut thin strips or small squares of paper, apply glue to the stick, and wrap the paper around it. You can mix and match different colors and patterns to create a vibrant and festive look.

2. Pom-poms and Ribbons: Attach small pom-poms or ribbons to the top of the biodegradable paper sticks. Use glue or double-sided tape to secure them in place. These colorful additions can make the lollipops look more playful and visually appealing.

3. Character Faces: Draw or print out small faces of favorite characters, such as cartoon animals or superheroes, and glue them onto the biodegradable paper sticks. You can also add googly eyes or small stickers to give them more personality.

4. Sparkle and Glitter: Apply a thin layer of glue to the biodegradable paper sticks and sprinkle glitter or sequins over them. Gently tap off the excess glitter and let it dry. This will give the biodegradable paper sticks a sparkly and magical appearance.

5. Personalized Messages: Write or print out personalized messages, like "Happy Birthday" or the child's name, and attach them to the biodegradable paper sticks. You can use colorful markers or print the messages on decorative paper or labels.

6. Cutout Shapes: Cut out shapes from colorful craft paper, like hearts, stars, or flowers, and glue them onto the biodegradable paper sticks. This adds a simple yet delightful touch to the lollipops.

Remember to ensure that any materials used for decoration are safe and non-toxic, especially if children will be handling the lollipops. You can also involve the kids in the decorating process to make it a fun and engaging activity for everyone.
