I use the clip-on magnifying glasses. I've used them for about 14 years and couldn't hand sew without them. I also use them when threading my Featherweight and when ripping seams. I have 6 pairs in various rooms. I couldn't sew without them. I have a stand magnifying glass which I never use and magnifying glasses that attach to my Bernina which I seldom use. Those clip-on glasses get used every day.
