Q #upcycling Judy (Customer) Peter (Customer) Kelly's Kelly (Shop Owner BD podshop James (Shop Owner) Frank (Designer) Maki (Designer) I want to be different. That's why I like to buy something special. I support the idea of sustainable development goals (SDGs). By buying this upcycled bag, I can contribute to the movement. Upcycled goods are well designed. They sell very well with trendy young people. It takes a lot of time and money to make upcycled items. As a result, they are expensive. I don't want to handle them. Upcycling is really challenging for us designers. The key is to hit upon good ideas. In Japan, we have been making new things out of old things for a long time. My grandmother made patchwork bags from old kimonos. Upcycling itself recycles an old idea.
