As you view the   different pictures, notice that a chair is not just a chair. There   are small chairs and large chairs. When estimating the amount of   fabric needed, there are many details that must be known. First   would be if it has a loose cushion for the seat and back, a skirt or   wings. Send me an email with this information and it will be   easier to estimate the yardage. As they say, a picture is worth a   thousand words.
