I feel so sorry for all the machines (sewing machines included) that are sitting somewhere in a box, I just want to adopt them all, or encourage everyone to get them out and use them.
Remember, just like your sewing machine, if it has sat for too long it will need oiling and a good run,
I have been around sergers a long time, My mom bought her first one when I was a teen and has actually worn it out. The repair guy said he has never seen one like that before. She loved it, did all sorts of dance costumes and swim suits as well as everything else under the sun. Once you get comfortable, they open up a whole new world.
So I encourage anyone that is sitting there looking at the box, open it and see what is inside.
