Pardon the dust.
I have to pull the bed away from the free arm of my sewing machine in order to get to the switch that lowers and raises the feed dogs for free motion quilting. On the inside of the body of the machine is this. It has a large embossed + and a - and a dial movable with a screwdriver that can be set to either or left in the (I assume) neutral position between them. What is it? My guess is it's presser foot pressure, but why is it here? Am I way off? And if I am, where is THAT adjustment done? Any thoughts?
Oh, and I found a few minutes yesterday afternoon to finish the quilting, then cut and attached the binding after supper. Maybe I'll have it done by Tuesday after all. Stay tuned.
