Got my overlocker (serger) about 20years ago and used it and used it and used it....for clothes for the kids, pillowcases, tea towels and winter hats. It was a godsend back when the kids were young as clothes were whipped up in no time and lasted.
Since I started quilting I have been tempted to sell it as I haven't used it in years. But it has been a very trusty, useful and well used part of my sewing life and think I may just start using again as I now have an embroidery machine and it will come in very handy when I get better at using that.
