No pressure on presser feet
I have a Bernina 1000 that my DH bought new about 25 years ago. One of many factors which caused us to choose it was how it sewed evenly over denim hems. I have only a little pressure these days. It stops when I piece cotton and it is very irksome. Does anyone know how to readjust it? There is a slotted knob on the top above the needle. I have turned it a little at a time in both directions and it makes no difference. Please help me if you can.
Thank you!
