Step 1: First, draw a straight line with a black brush on the prepared drawing paper, as shown below.
Step 2, then continue to draw several irregular arcs on the line, as shown in the figure below.
Step 3, then draw the overall outline of the grass, as shown in the figure below.
Step four. Then draw more lines on the basis of the grass just drawn to enrich the shape of the lines, as shown below.
Step five, continue to draw a few small stones on both sides of the grass to enrich the picture, as shown in the figure below.
Step six. Finally, paint the drawn grass line drawing with beautiful colors with colored marker, fill the grass with green marker and fill the stone with brown marker. Here is a sketch, as shown in the figure below.
