Here’s a slick way for one carpenter to walk a wall while installing blocking with a minimum of wasted effort. As shown in the drawing, I start a 16d nail in the corner of each block at the angle required for toenailing. Next, I put a nail partway, into each stud just below the location of the blocks. Then I hang a block on each one of these nails, using my angled nails as the hooks. As the blocks are picked off their nails, their hanger hooks are driven home as toenails.
