The project is fixing fairy lights to a traditional stone outbuilding. The idea is to light all the edges of the walls and roof, producing a lit outline. About 60 metres of lighting all told. This will be a semi- permanent installation.

've never done anything like this before. My first idea is to use zinc- plated steel eyes, screwed into yellow plugs. Then fix the cable to the eyes using plastic cable ties. To make the eyes inconspicuous I'd probably screw them into the mortar rather than the stone, every 50cm or so.
Anything wrong with this plan, or suggested improvements?
