Negitive space drawings

A. When you look at a stool for example positive space is the object and negative space is the what you look through.
B. I think it was easier finding negative space and making the drawing with the cut then the stool drawling. I found negative space with the stool by drawling it in positive space first then it got easier to find because you just had to fill in the spaces on another piece of paper. I found negative space with the cut out by tracing the one side and cutting it out  and putting it the other side of the paper.
C. It helps you with abstract drawings.
D. It enhances the drawing because you get to see it in different views and that makes you know more about what your looking at or if your actually drawing it.
