. . . for me it means to create something new from already existing things. This can be something useful in the household, clothes, decorative objects or something that helps with research. In my opinion, it also depends on how you deal with the resources you use for your project, i. e. being able to estimate the amount and not use everything in excess. Perhaps you could also say that you can make a lot out of a little. With Sustainable Aesthetics, I also think of variability, that is to try out a lot and venture into projects that you have always been interested in or have never done before. In my case, this would be woodworking or modelling with damp clay.
