Hey guys, I need a crash course in string lines and laser levels. I know bits and pieces from classes and pictures and stuff but I still could use a better working knowledge of the procedures and how they actually tie in to building a hardscape. What are all the steps from setting up a laser level to using it to pitch the patio? Where do you put your string lines and how do you apply them to the construction in various applications? Things of that nature. I also thought this info would be good for anyone else who was on the learning curve too. This is where I am a strong believer that no amount of icpi, ncma, (I have both), supplier classes, trade shows, etc can be substituted for good 'ol experience. And since I'm still working on the experience part, I tend to go ask guys who already have it figured. So have at it, tell me everything you know, post illustration pics, links, whatever. Thanks in advance for the help.
