We were at a Flea market this morning. One of the vendors had a sewing stool with a bunch of sewing things in it so I started looking at the feet. There were several that look like they might fit a FW so I started looking for numbers thinking that they might be familiar as I was working with them this week. There were no numbers and then I realized that they were shiny looking as well. Does anyone know anything about new feet? Are these repros out of China? I wonder about quality?
