Zhiyuan Wang_ Making 10 Money boxes

First step is make 10 copies of my design. Copy is not simple as I expected, it needs me focus on every step, such as assembling the mould, pouring the plaster into the mould. Furthemore, time saving is another issue, cause making 10 money boxes takes lots of time waiting, so I need to use the time efficiently. For instance, when I wait for the plaster dry, I can clean the previous one and make coin slot. During this step, I had one money box failed, because I spent less time drying it. In conclusion, you still need patience when you doing something looks like simple.
