I purchased a quilter's Curve Master and an invisible zipper foot that require an adapter for my Bernina 1000. I bought the adapter at a Bernina dealer, although it did not appear to be manufactured by Bernina. When I attempted to use it with either of the above mentioned feet, the feet rotated counterclockwise. The dealer said, so it doesn't work buy a Bernina invisible zipper foot. I returned the adapter.
My question is: Is this a universal problem or just a poorly manufactured adapter.
Any one have a similar experience?
