2019 – Self Knitted Scarf of Train Delays

The mother [of] Sara Weber knitted this scarf during her daily train rides to work in Munich and used different colors depending on train delays. Every day two rows: Grey, less than 5 minutes delay. Pink, 5 to 30 minutes delay. Red, both rides delayed or one more than 30 minutes. The huge red area was during construction work, where the train was substituted by a bus.
Side note: The tweet went viral and at the end she sold the scarf at eBay and gave the money to the "Bahnhofsmission" who take care of homeless people at trainstations.
