The crate system - Visual communucation

 The crate system is a technique you can use to draw something that looks in perspective and proportional. It is great for something like a perfume bottle. You start  with a very spread out 'y' shape (see in right picture) and draw the rest of
                                          the lines coming slightly closer to the one next to it to show perspective, once
                                          you have your crate shape, you can draw anything within it, following the lines.
                                              Once you have drawn a main shape, for example a perfume bottle, you can
                                          begin to draw the background too, still using the original lines as a guide.
