Beading How-To

My daughter bought her wedding dress this weekend. It has beading around the neckline, and we were thinking about doing something similar along the hemline and maybe around the edge of the train. I`m a fairly experienced seamstress, embroiderer and beader, but I`ve never done this type of work before. Does anyone know of any websites that would have information on how to do this, materials to use, etc.? Or maybe some books that would have this info? Thanks for your help.
