Just a funny note. I have a Elna serger and had to take it in for service. I have my Singer and Brother machines that sits on the table as well. They are plugged into a power strip serge protector. When I brought the serger home and pluged it up, I accidently picked up the Singer power cord and plugged it in. It came on sewing! I was furious with the repair man. I thought I just spent my hard earned money to have this thing fixed and it is worst than when I took it in. It would sew great but, I had to turn to power source off to get it to stop sewing! I took it off the table and ready to take back to the shop the next day. That is when I discovered I had it plugged up with the wrong power cord!! Talking about LOL!!!
