I use them for a lot of different things.
Sometimes I make to do lists for a day, or maybe even a week. I often use them when I read a book in another language and write down important vocabulary. Every now and then I'm also just jotting down my thoughts.
bought more than i've used.
I plan on putting them in ever room of my house, a few for when i need to buy things for that room, others for ideas or what i need etc. But i absolutely LOVE postits..they're time savers!
