This is the first time I have used perspective lines in my drawings so after reading the notes about perspective I chose a doorway and checked the angles and foreshortening before continuing with this exercise. I drew freehand and from the image of the doorway extended the lines to be sure the perspective was as accurate as possible. The best view I have for doors is upstairs so I took my ‘drawing’ chair and sat in the hall and all the views of the door into the bedrooms looking in. This is because upstairs is quite small so I found it easier to sit down looking into a room and I also took a small stripey rug (which is not usually there) and placed it in each room, as advised for some added perspective. I included a bit of additional information such as the angle of the doorway and walls both inside, outside the door frame and furniture.
I did the first sketch using 8B pencil, the second sketch is in black ink, and the final one in 2B pencil, all in my A4 sketchbook. I used the ruler for all the sketches but for the last drawing added a red pencil to highlight the extended lines over the top and I was pleased to find the lines met for a one-point perspective towards the vanishing point. This exercise for me is to help discover how accurate my guess work is too, having said that my sketches were simple linear works but I wanted to understand how the simple one-point, parallel perspective can be to use, and from now on in my sketches, it can be incorporated into drawing buildings and structures in general.
