According to the video, you can use string to create straight lines. Greg demonstrates how to make a loop at the end of the string and hook it onto a nail or screw. Then, rotate the string with one finger and pull it tight to create a straight line. I also provides tips on how to loosen the string and how to make it tighter.
Here are some bonus tips:
You can use straight lines for all sorts of things, including building fences, foundations, and long walls.
To make the string tighter, rotate it more times before pulling it.
If you need to make a really long straight line, you might need to rotate the string between 8 and 10 times.
You can use both hands to pull the string tight, one to push and one to pull.
If you need to loosen the string, just pull it in the opposite direction.
