In this video, we learn how to do a grass silhouette effect in GIMP. First, draw a black mound and then close off your selection. After this, turn the path into a selection and fill it in with a black color. Next, select your smudge tool and use a small circle brush. Set the rate up to 95, depending on the length of grass you want. Now, use your mouse to push up on the mound and you will see wispy pieces of grass form where you are moving your mouse. Cross them over and cover as much of the area as you want. When finished, you will have grass, then save your image and continue on!
