I have knitted wears shrunk to a size fit for a child because my ex-maid kept forgetting that you cannot dry woollies in the dryer. Writing about it, I am missing my Edmund Ser's polo neck. I bet you have sweaters stretched out of shape to complain about too.
Other than unraveling to salvage the wool to recreate, what else can you do about it if unraveling is too daunting a task and you are not good at crocheting or knitting anyway?
