The line is one of seven art elements. The other elements are shape, color, texture, form, value, and space.

Instructions: Practice drawing straight lines and curved lines. Straight lines move in a single, level direction. Curves are lines that gently deviate from straight. A curved line may crisscross itself. Lines can also vary by length, width, and texture.

Materials: Drawing paper and drawing implements such as pencils, fine-tipped pens or markers, or charcoal.

Keywords: Line, straight, curved

Step 1: Draw a straight line.

Step 2: Draw a line with a gentle curve, as shown.

Step 3: Draw a line with a bigger curve, as shown.

Step 4: Draw a line that curves so much it crosses over on itself, as shown.

Step 5: Draw two lines of different lengths - a shorter line and a longer line.

Step 6: Draw two lines of different widths - a thin line and a thick line.

Step 7: Draw two lines of different textures - a solid line and a dotted line.

Step 8: With a fresh piece of paper, draw anything you wish, but incorporate at least one straight line and curved line into your artwork. Use glue, scissors, colored paper, markers, paint, or anything else you desire to create your artwork.

See below a painting with straight and curved lines by artist Piet Mondrian, entitled 'Gray Tree.' Can you identify the straight lines? Can you identify the curved lines?
