Another great idea that I found in the book Häkeln + Stricken für Geeks: the stretch sensitive bracelet.
Very handy now that’s longer dark outside: as long as it’s light you wear it as normal non-shining wrist warmer and when it get’s dark, you shove it up your arm and then the light begins to shine and you’re better seen.
