I've been surfing the Janome 6500/6600 user's group at the suggestion of a friend. Man! The stuff I've been learning. I didn't know my machine could start sewing all on its own when my back is turned! This happens when there's a short in the foot control or a sensor failure in the machine. Weird!
I've been fit to be tied because my machine won't sew over patchwork that has more than four layers without either chewing the edge or 'jogging' around the intersection. Maddening! Adella my featherweight does the job like a dream, so I *knew* there had to be a solution. I drove the hour and half to my dealer and the showroom machine didn't do it. So after much talking about needle size and downward pressure on the pressure foot they told me to bring it in. "Maybe there's an adjustment we can make, we'll see..."
The price of gas being what it is, it costs $55.00 to drive to the dealer. I told DH what I needed and how I thought it might be done and away we went.
