The paper is quite white but is showing gray in this photo. Mom was sitting in the recliner, visiting for a little while before beginning her quilt project, so I tried to do somewhat of a gesture sketch to show the position of her body in the chair. I had not sketched her arms when she decided it was time to get busy and left the room. And no, this does not look like Mom's face.
I have been doing a lot of reading from different books on drawing the figure and the head. I am somewhat stymied on setting up a grid for 1-point perspective for figures. I know that the farther away the lines are such as a railroad track the narrower the lines become until they converge at the vanishing point. Also, the horizontal boards appear farther apart up close but as they progress into the distance the space between the horizontal board narrow. So how to figure out how much they narrow on the ground plane. Did I mention that math is not and has never been my thing? In the photo from Loomis, pg. 48, one can see how the both the vertical and horizontal lines begin to narrow. Anyway, that is my challenge for today, figuring it out.
