Goodness, had to make sure and get the “Sweateuw” spelling right. Anyway, a lady in the UK named Jan Brown decided to start making them for ResQte Greyhounds back in 2008.
In 2012, she quit her job to knit fulltime, and started Knitted With Love.
Quoting the original Design Taxi story, Brown says “Greyhounds have very thin fur so they really feel the cold during the winter so my gifts help keep them warm during walks. There are so many dogs that won’t be rehomed this Christmas so for many of them it’s the only gift they will get.”
