I bought a serger about 5 yrs ago thinking how much I would use it....not.....it now sits with a dust cover on it.....once had to rethread....5 hrs later....still no luck...had to take it back to store and was rethreaded in less than 5 minutes, so hint about tying that thread and leading thru paths is a great hint. I honestly cannot remember when I last used the dumb thing....of course I only quilt, so why did I think I needed that monster...........
