I am building my own concrete block garage. And when it came time to lay the first course I did not like the string method for it depends too much on eye judgement. So what I did was haul out two very long and stout plumbing pipes. Very long stiff and firm and layed the block loosely for the first row and then instead of string and eyeball I simple rolled the two pipes, one on the inside of the row and one on the outside of the row to make a "perfect line".
That method is great for the first course because the pipes are on the concrete slab.
Now, I am trying to figure a way to use the pipe method going up the wall so that I never have to use the time wasting and imprecise string method.
Thought I might share that with you so that we do replace the old string method with something easier, faster and better. A method where the test uses the material instead of a "eyeball judgement call"
