I know a lot of people like the small filament tags with different holes to check how opaque it is, very small ones to minimize filament usage or ones with holes so you can put them on a keychain.
I prefer a more simple design and don't mind spending a bit more material.
I print one of every roll of filament I start as a little souvenir and a very good reason to start a new roll :)
