Measure and Mark Wall Center

what I've got to do is find the center of this wall to begin with so I'm going to measure out find the center and then we're going to begin because the center is where my squares are going to start they're start on the center work the way up and work the way out from there and then once we get the center figured out then we're going to begin marking I'm going to have 12 in squares I'll begin marking you know 12in lines down the wall and then 12in lines across the wall and that will actually lay out our squares so first thing we're going to do is find the center of this wall so I'm going to go from you know one edge of the baseboard to the other Edge I'm going to se it comes out to it's 130 in half that is 65 in and and I know 65 in down here now a simple trick I'm going to lay this level right on 65 in and in order to find the center of the wall I'm going to take my level move it back and forth at the 65 in Mark make sure it's on 65 once the level is level I can actually mark my Mark at 6 at 65 in so so again I'm going to get it down here make sure it starts at 65 move it over now I see got it level make a mark and that's the center of my wall right there so that's the center point first square is going to be centered right over that now I'm going to begin
