Grid Drawing Method in Art!
Children have been developing observational skills by creating tonal grid drawing during Art lessons.
The grid method involves drawing a grid over your reference picture/photo, and then drawing a grid of equal ratio on your work surface/paper.
Drawing complex objects purely by eye, without any visual aid like construction lines, or a physical aid like a proportional divider can be difficult.
However, using the grid method can help with drawing objects or pictures which require accuracy.
