My older machine is a singer treadle the 12k family dated back to the 1800's and in working order!!!! The reason I am thrillle dthat its in working order is...you never know when something might happen to where you are without power. And as we all know the treadles don't require electricity! So...if need be, I could continue on with my quilting. I might have to light up a oil lamp,but power outage wouldn't slow me down.
