I am trying my best! My internet has been absolutely crap lately, and on top of that, I’ve been getting increasingly busy. I have a ton of new content to post soon, so be ready for that!
I’ve never had a single issue with using fairy lights, and neither has anyone else I know, so I can only assume that they burnt out because a) they were faulty or b) because of age and overuse. I’d definitely consider purchasing new ones since there are so many energy-efficient varieties so you can be certain you’d be safe. Good luck!
You could try using a stronger tape such as painter’s tape or double-sided tape, or you could use Blu-Tack or maybe even glue dots.
