What kind of serger did you have?
I have trouble seeing too. I always wear bifocals and can’t read a thing without them.
I have a Brother 1034D. It’s very easy to thread, especially if you remove the presser foot first.
It was the Swiss one, rather expensive. Bernina, wow, hadn't thought of that name for years. I couldn't think of Bristol Palin's first name when I woke up and am worried my memory is starting to go, then after I got up it came to me. There were too many threads going, 3 or 4. Not FR threads lol. You know what I mean. I wear bifocals, too, but didn't for most of my sewing days. If I'd really put my mind to it and used a threader and magnifying glass, I probably could have mastered the thing. But I just didn't like it, had to get the tension right, loaned it to a friend, she died, husband or one son called me and asked if I wanted it back because somebody close wanted it. I said let her have it.
They did so much for my son when he was growing up, took him in, really a great help to me in tough times.
I never looked at the Brother; I think that was a good brand, too. I've seen the wonderful things that can be done with sergers but enough was enough for me. They cut and overcast at the same time; I didn't know what to do at the ends to keep them neat; I'm really a perfectionist about my sewing. I've always had too many irons in the fire, too many projects going.
