I've been asked to embroider names and the title of the employee on some t-shirts. They want me to put the name on the top line, and title on the second on the front of the shirts. Both lines of embroidery are to be placed on the left side of the shirts. If they had pockets, I could figure it out, but they don't have any. They will be different sized t-shirts. Can anyone tell me how to know where to put the lines according to the t-shirt size, as to not have someone's name either too high or too low on the shirt?
