How to Draw Seaweed
When drawing masses of seaweed, the form can be depicted with rounded shapes that encompass the tendrils. (Jupiterimages/ Images)

Add spice to your aquatic life scene by drawing seaweed. This flora is so prevalent in the ocean depths that no drawing of underwater sea life would be complete without it. Drawing seaweed is easy for the beginning artist because of its usually simple shape. It can be created from a single curved line that is used as the underlying structure for the "weed" shape. A few strokes from the pencil is all it takes to create the foundation for some beautiful seaweed drawings.

  1. 1

    Study your seaweed reference in order to understand the shape of the flora. Draw curved lines based upon the curvature of the seaweed.

  2. 2

    Use the curved lines as the structure for each seaweed stalk. Imagine that the curved lines are the centre most part of the seaweed stalks, around which the form exists. Draw the outlines of the cylindrical stalk shapes around the curved lines to create the forms. Seaweed usually appears to have a tendril shape that can later be made three-dimensional by depicting them as cylindrical shapes.

  3. 3

    Erase the structure lines. Look for shadows and texture in the reference and shade the drawing to reflect this. Shadows can be created in the drawing by turning the pencil on its side and creating soft, broad strokes. Texture can be added with small lines drawn all over the seaweed.
