I have a laser level that I’d like to use for lining up pictures on my wall. I’m doing this by myself otherwise I just have someone else hold it. It has a couple holes in it that look like maybe you could use screws or nails and I’d rather not have to put holes in the wall to do this. Any suggestions?
The tripod idea is a good one. I’d suggest just stacking a bunch of stuff up on a table or chair. Or, if you have a tape measure, mark a control line around the perimeter with painters tape and measure up from there.
