Lisa, I know nothing about sewing machines but a little about hand stitching. There are many ways to improve the speed and quality of our work if you are interested. First I would say to use the pricking iron only, not a combination of the wheel and the iron. As you say, they do not always quite match. If you could provide more details (pictures would be great) on your issues with sewing/stitching I'm sure the resident experts will be more than happy to help. Hand sewing can be quite fast -- I've clocked myself doing better than 3 stitches per minute at 10SPI. No idea if this is 'good', but seems like it's faster than a lot on here are achieving. Not as fast as a good machinist, but then the investment cost is much lower
