Here is a Youtube video showing how to wind the bobbin, load the bobbin into the machine and also how to thread the machine on a Singer 301.

I really love the 301's....it's such a simple and basic machine. It only sews a straight stitch so if you wanted to do zig zag stitching you would need the attachment for that or get a different model.
