Just some observations about presser feet if anyone is interested.
Sometimes I've had to buy new presser feet for my machines. Some of them have come to me with the bottoms of the feet just chewed by the feed dogs. Some can be polished down, others have to be replaced.
I got my last Sew Classic order yesterday. I had ordered some of the generic low shank ZZ feet with the curled up toes and one high shank one too. They looked really good, fit OK and worked good too. I had a magnet handy for something and started checking the feet.
A lot of them were made from aluminum or some other non ferrous metal. Some of them had steel feet with aluminum shanks. Some had steel shanks with aluminum feet. And some had an aluminum shank with the feet made from some alloy that just barely attracted the magnet.
Then there were some that were genuine steel that about jumped at the magnet.
Visually, you can't tell them apart. They are all chrome plated and look nice.
I just hope the aluminum and bi-metal ones last as long as the steel ones.
At least you can see the plastic ones and ignore them if you want to.
