Looking at a DIY quilt project this summer and was thinking of salvaging down from a couple old parkas and sleeping bags. I am guessing there will be a mix of Duck and Goose Down. Is there any method for checking the down to see if it is still good or usable? Any info appreciated.
I found a few threads on salvaging n such. I am going to be salvaging from sleeping bags so quilling should not be a heavy issue. I am more concerned about the quality of the down. i.e. has it been damaged from improper washing, degraded, etc. etc.
