Excuse my ignorance, but how would one go about this process? With cotton you can use simple bathing tub/washing machine options, but from what I've understood, re-dying wool clothing is a rather messy/painful task with more uncertain end results (with regards to the wearabilty of the garment) - if there's a comparable easy way I'd be interested in hearing about it.
