Never knew draw drapes went out of style, but I used to make drapes. You also haved to add 3 1/2' for turn around of rod. I did 3 1/2" space between pleats and 5" for each pleat. Please do not use the pleater tape. They never hang like a custom made drape. Also you do the hem before you put in pleats. That was always a 3 1/2" double hem, for better hanging. That is the professional way of doing them.
