The ONLY machine I sew with is a 1941 cast iron Singer. I own 4 other machines, bought with the hopes that I could do more than straight stitch with them but since I just don't have that mechanical "fix it gene"---or the patience to experiment til I get it right----I use the old machine since it is 100% reliable as long as I remember which way to load the bobbin...note to self: the thread comes over the bobbin TOWARDS me! Have made lots and lots of quilts with it and its only problem is that a couple of years ago, it got balky on making bobbins since the little notch thingie that holds the bobbin on wore down too far.... so I bought a bobbin making machine. Also replaces motor and foot pedal a few years back. Plan on using this one til I die----which I'm sure will be before this one gives out!
