There are several simple tricks you can use in order to more effectively communicate to the people around you what you expect and train them to do it. Notice here I started with communication, it is critical to success. It doesn't matter whether you want red velvet cake or a beach house, the more clearly you can describe and communicate your desires to other people the more likely they are to be able to produce what you expect.
The first step here is to describe in as much detail as possible exactly what you want. Do you want that red velvet cake as a cupcake, a 9 inch three layer cake, or a sheet cake. Look at how something as simple as a red velvet cake can be interpreted three different ways.
