OK, the only pearl of wisdom I have is my recent discovery that horizontal bobbin machines are really bad at sewing with heavy thread. I assumed it was always so difficult as on my 201, but then used a vertical (Pfaff 360) and the difference was amazing. The 201 did it (pair of jeans) but it wasn't easy.
Pfaff handled a second pair easily, then a friend told me about the horizontal bobbin thing.
