There's many different opinions about yes/no spreads and whether we should do them. As a reader it is inevitable that eventually someone is going to ask you a yes or no question, some readers refuse to read for these instead having their querants revise the question so it's open-ended.
For those that do read these questions there are two main popular methods. The first is using upright cards as "tick points" for a yes and reversals for a no. Based on how many of these cards appear in the spread determines whether the answer is a yes or no, then the cards are read to give further insight into the answer. The other method is to do a basic 3-5 card free-form reading, in this way it is upon the reader to determine the answer to the question.
