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?
They make new ones now with a battery powered vacuum built into it. Maybe look into one of those if you use the laser often.
In the meantime, you can use a wide variety of things. Painters tape if its light enough, a camera tripod, stacked books on a desk, nails though the holes as you suggested, all valid ideas.
