Label them right

When I was a kid, I remember having so much fun with Dymo labels. Mom bought me one and I started labelling everything I could think of sticking that little piece of yellow strip on. And then I'd be so proud to show them to friends because not everyone would have such labelling tools. But nowadays I guess this isn't quite popular anymore. Instead, I see a lot of youngsters going for nice artsy stickers to put on their phones, laptops, and whatever gadgets they might have.

How do you label your stuff? I've gotten out of the habit by now... :)
