If you like to draw outside, use circles and ovals to sketch flowers quickly and easily.
To draw a four petal flower as seen from the top, lightly draw around a large coin (I used a quarter) and then make two crossed lines that divide the circle into four sections.
Draw petals around each quarter as I have done.
Finish by erasing the circle and crossed lines, and then add few dots with the tip of the pencil to create stamens at the center of the flower.
To draw the same flower as seen from a side angle, draw an oval and add crossed lines as before.
When you draw petals around these quarter lines, the one that “comes at” you, will be epsecially short. That’s called foreshortening.
The petal on the opposite side is forshorteded too, since these two petals are on the same plane of the drawing.
The flowers you just drew were flat and the petals of most flowers angle up. To draw angled petals, draw the same oval again but mark a lower center point with the pencil tip and then connect the quarter lines to it. (It will look as though you’ve pressed the middle of the lines downward with your fingertip.)
To draw a flower with longer petals, move the center mark below the oval.
A flower drawn this way has depth and three dimensionality, as you can see when the petals are added.
