There are two large spots where the chrome is worn off and it is obvious that the spring has lost its ability to "bounce" very fast at all. I am glad that it only costs about $14 to buy a new foot and very relieved that I wasn't facing an expensive and inconvenient mahcine repair!
This experience made me think of my dear friend, Monet, who literally broke her machine beyond repair when she did pebble quilting on a baby quilt. She really had to argue with the store she'd purchased the machine from - insisting they honor the warranty she had had. They tried to give her back the machine when it still wouldn't do any free motion quilting - but she fought back and won - and they ended up replacing her machine!
