Gosh Tammi, I don't know what else you could say about the 403A. I didn't realize that you had all those other vids up there already. It's a pretty carefree machine, so I guess you've covered it. Do you do sewing machine repair classes/courses that go beyond the basic videos? How about online ones? If not, you should. You're a far better teacher than the person I took a class from last year.
