Re-stuff a down vest?
I bought a wonderful down vest from J Crew 8 years ago, and after many years of washing and wearing, it's not looking quite as lovely and fluffy as it once did. (I've always dried it with tennis balls and treated it nicely.)
Question is, can I add more down or replace the down? I've spent an hour searching online for advice on how to do this, and haven't found any info. Anyone tried it? Is it as simple as taking out seams, filling and sewing it back up?
