In the era of online shopping, plenty of carton boxes pile up at home. Rather than spending money on new plastic toys, it is better to use cardboard waste to DIY a one-and-only toy.

My son loves ships, so I used cardboard to piece together a large ship. He acted as the artistic director in the entire process.

How big is the hull? How many cannons are there? Fleet number? Putting the chimney a bit forward or backward? Which parts to be coloured? What colour? Which parts stay uncoloured? What national flag to be painted? It’s all up to him and we worked together. In the process, creativity, aesthetic appreciation and agile Hong-Konger adaptability were cultivated, whereas environmental awareness could also be instilled.

The project was concluded with the father’s and the son’s signatures on the hull. It was completed within one day with a budget close to zero but that moment was priceless, unforgettable for a lifetime.
