We firstly defined a 2cm*2cm grid, then tried to sew each chosen point and made this cover. Unfortunately the stirrer didn’t work, so we added 175 gram extra water to make it flowable. We poured concrete into fabric which we made some smocking to give it an amazing surface.
We poured concrete onto the cut plastic cups. After two days, we found it too soft due to the too much water, so the main question in this casting is the amount of the water.
