Isac Walter's Minor Thread website documents his current attempt at wearing a different t-shirt every day for as many days as he possibly can. He has so far made it to 555 days, although he is still counting.
According to the Minor Thread website, Walter will continue on with his project indefinitely. Although he has made it past the 500 mark, he will perhaps continue until he hits 1000 days. He asks readers to partake in the initiative via his @theMinorThread handle.
Walter has worn mostly vintage pieces, part of which he has taken from the 'wanted' section of his page which lists shirts that he is intent on buying. And so, the end of Minor Thread has yet to be seen.
