With the string lights from Kosmos, your creativity knows no bounds. You can craft colorful wool balls with your children and illuminate them with LEDs. This creates your very own design that you can use perfectly as decoration. For the grid balls of the string lights, the included balloons are filled with air and then wrapped crosswise with wool. This wool must first be soaked in a special hardening mixture. After the balls have dried, the balloons are popped. The final step is to attach them to the string lights by threading them on. In no time, your very own string lights are ready and shining in vibrant colors.
