The ship(s) are owned and run by a nonprofit: http://longshipco.org/. We are in the water from ~June to the end of November, so if anyone is in the DC/tidewater area and wants to go out, drop me a note.
I have one or two dyed things that I may add to my shop if I get around to taking photos fast enough...
Bad smells could be any number of things, but you should probably take it in before something breaks horrible or the machine catches fire, etc. I am a heavy user of my sewing machines and tend to wait longer than I should to have them serviced, but bad smells, along with clunks, are a sign that it needs to be seen by a repair person asap.
Also: things I am on the lookout for: holiday cards cold process soap cat toys (new cat is a toy fiend)
