Mrs Tkk put my down jacket in the wash. She followed all the instructions but it still came out knackered with the down in clumps.
First I knew about it was when the postie delivered a package and she handed it to me saying " this is for you " and telling me about the laundry disaster. It was a lovely down jacket from Alpkit. I've not worn it yet apart from trying it on, but it felt toasty when I did.
Meanwhile I dug out the original " ruined " jacket, rewashed it as recommended, and then did a short tumble dry / shake and tease out the clumps / tumble / shake / tease until the jacket was back to its former state. It's become my house jacket/ outdoor garden jacket. There's several bits of sticky tape where I've snagged the jacket and tiny bits of down were poking through, but it's sort of my favourite " do anything " scruffy top.
