In this tutorial we learn how to draw a glass bottle. To start the bottle, you will draw the outline of the bottle starting with the cap to the base. After this, start to shade in the top and around the sides of the bottle. Small lines will create the effect of the bottle seeming to be transparent. After this, start to shade in around the sides of the bottle and on the bottom. Draw the inside lines and the other side as well so you can see that it is clear. Then, use the eraser to smear the color of the shading and you're done.
