I have a Necchi I bought when my kids were little. I made snowmobile suits for them to play in the snow. And ... back then that material was really bulky.
I made fitted Herculon upholstery pieces for a couch and chair we were given waaaaay back when.
That machine is still going stong!
However, I now use my Pfaff's and FW as they are much lighter. Well, not the CV, but it is stationary in my studio and doesn't travel!
