I was recently given a "hand-me-down" L.L. Bean down jacket and vest with 80% down fill (not sure of the fill power). They are in really great condition and puff up pretty high. I was thinking of how I can turn this into an under-quilt. Do you think it would be wise to source the down from the coat and vest and use it for a DIY under-quilt? and if so what would be the best way to remove the down?
