No chapter folding bag white

I used to read a detailed introduction to some unnamed designs in my life in a book. And what I am most interested in is an introduction to paper cup design. The basic design concept of paper cups is actually very simple. It is a container made of two papers with a cup edge (long trapezoid) and a cup bottom (circular), but the most special one is a clever design on the edge of the cup. Curving the paper outwards increases the strength of the mouth of the paper cup, so that the paper cup is not twisted in the hand, and another function is to make the lips not be scratched by touching the sharp edge of the paper. The concept of such a simple and accurate made me extremely shocked, so I tried to extend the concept of paper cup to the design of the canvas bag. Folding the fabric outwards would not allow the canvas, which was not too thick, to stand still. Too soft. In fact, the beautiful materials are always there, and only a clever combination can make the objects appear introverted and just beautiful. Size / W29xH19 (cm) Origin / Taiwan
