Right, time to restring up my fairy lights with a far better solution than the one I had before. nailing in wire holders was... awkward. in the extreme. and several have broken.
gonna try some stick on ones instead
@Nine oooh! That does sound pretty tbh!
it worked and now I have the lights strung up nice and in a line without dangling and they're now like, visible from both sides of the beam. ^^ it's nice.
