Q: Although you can certainly create a stippled drawing from an imagined image, it is much easier to do so with a hard copy to examine as you draw. Outside of determining where figures and objects are in the composition, you'll need to look for a few other important elements. With your drawing laid out in front of you, look for: The light source and the direction of the light. The light will determine what areas need more stippling and what areas need less. The value of the drawing. This is where on the grayscale each of the colors (or shades) lie - how dark or light the colors are. Value is closely related to light. The shapes in the drawing. You'll be creating all the figures and objects without using any lines, so pay attention to the shapes that compose the figures, and recreate them with your stippling. Because stippling is just the process of creating hundreds of tiny dots that make up an image, you can use many different media for creating the dots. Higher quality pointillism pieces are done with more dots per square inch, meaning that they were made with a drawing utensil that allowed for very small dots to be made. Keep this in mind, because although you can use about any medium you want to create your image, the smaller the mark that is made, the more realistic your image will look. Possible media for stippling include: A fine point pen. Most artists who do high-quality stippling use a pen with a .03 or .005 inch (0.0cm) nib. This allows for tiny dots and plenty of shading. Pencils - colored or otherwise. Although by using pencil you run the risk of smearing the graphite and blending the color, you can use it to create small dots. Colored pencil is less likely to smear than graphite, and will add a bit more interest (and difficulty) to your image. Paint. Paint is typically considered the most difficult medium to stipple with, because it is much easier to accidentally create a stroke/line than it is with pen or pencil. Before you start making any dots, you need to decide how dense you will draw them. A more detailed image can be made with a higher density of dots. Keep in mind that an image with lots of dark values will need more stippling than an image with plenty of light. Try doing a set of dots on a piece of test paper, creating different shades of gray (or colors, if you're using colored pencil) by spacing out the dots different amounts. You can then reference this test paper as you create your final project. The higher the density of dots, the more time it will take to recreate an image. If you don't want to put a lot of time into the project but still need dark values, try using a pen with a larger nib (such as .1) or a different medium that creates larger spots.
A: Evaluate the image you are recreating. Decide on your medium. Decide how dense you will make your dots.

Q: To do this, place the compass tip on the given point on the line. Then, swing the compass, drawing two arcs on both sides of the given point. The arcs should intersect the line. Mark and label the points where the arcs intersect the line. You can set the compass to any width for this step. For example, you might be given point A on a line. Use the compass to draw point P to the left, and point Q to the right. Place the compass tip on the new point to the left of the original point. Stretch the compass so that it reaches about halfway between the original point, and the new point on the right. For example, place the compass tip on point P, and stretch the compass to a point about halfway between points A and Q. You could also draw the arc below the line. Keeping the compass tip on the left point, swing the compass, drawing an arc. Make sure the arc crosses over the original point. For example, keep the compass tip on point P. Draw an arc above the line. Do not change the width of the compass. Set the compass tip on the right point. Swing the compass, drawing an arc above the line that intersects the first arc. Mark this intersection with another point. For example, place the compass tip on point Q. Draw an arc that intersects the first arc at point T. Use a straightedge to ensure the line is straight. The line you draw is perpendicular to the first line, through the given point on the line. For example, draw a line connecting points A and T.
A:
Draw an arc on either side of the given point. Increase the width of the compass. Draw an arc above the line. Draw a second arc, intersecting the first. Connect the given point to the point where the arcs intersect. Finish up with the construction.
