Miriam, Four Elnas that don't work?? That's scary. I love my Elna and would feel bad if she wasn't her perfect self. My friend's Elna, a year older than mine is having problems, too. Besides, Miss Elna is my only zigzag machine.
I wish I'd known about your tables before last week. My son got sent home from Alabama. He had to come through your area and probably won't be making the trip again for another month.
