I've had my current sewing machine for about five years now and have never used it to it's full potential. It has eighty five different stitches, as well as a button hole facility and an alphabet setting. In the instruction manual it shows some ways to use the embroidery stitches that I just can't get the hang of.
You can see in the above, examples of using the memory to do a symetrical sequence of stitches. There is a button that you push to do a mirror image of the chosen stitch but it just makes the stitch upside down. So, this is going to take a bit of puzzling out. I do have an idea that I came up with earlier and tomorrow I will try it out.
