This is an idea I wrote down a while ago in my craft journal. It's been so long since I came up with the idea that I'm not even sure what made me think of it. I suspect I was brainstorming things I could make with Japanese masking tape but who really knows. Anyhow, these twist ties are super easy to make. I think they would be great for favors, especially if you have a specific color theme.
