The 1963 Husqvarna is broken. I figured out why I couldn't adjust the stitch width or back-tack - the knob that controls those is broken. It think it's worth getting fixed - I've had a sewing machine shop recommended to me that I will give a try.
But in the meanwhile... since my birthday is coming up and all I have decided to get a new sewing machine. I found one that does small embroidery as well as sewing a whole bunch of stitches - the rother SE400. It also has very good reviews. So if anyone wants to get me a birthday present - I humbly suggest an Amazon gift card that I can use on this puppy.
