Step 1: Draw the edge of the plane and the lining cloth of the rear elevation, and then draw the still life modeling through the simple geometric shapes practiced in the basic stage to determine the overall composition. At this stage, we used the geometry practice stage in the course:

Step 2: Draw the edge of the interlining with clear lines, describe the shape of the object in detail, and draw the dark side. Then draw the dark side of the sandwich fold and start drawing the dark side of the bottom of the glass plate. Gently draw the dividing line between light and shade of fruit with a pen, and roughly spread the light and shade on the red wine bottle.

Step 3: Deepen the dividing line between light and dark, and at the same time start to draw the shadow part. In this step, you can describe the details of the object, such as the pedicle of the pear, the thickness and cross section of the glass. The inherent color difference of interlining should also be widened, and the color blocks of dark interlining should be discharged with lines.

Step 4: Depth description, showing the brightness relationship of the picture. The shadows of the board and the interlining are clear, and the fruit maintains a consistent light and shade relationship with the whole painting.

Step 5: further depict the details and adjust the picture as a whole. Transparent objects are translucent. Because of the transparency of glass, the color tone is lighter.
