I learned how to sew in the 50's. I had to thread the needle, cut the thread, etc. myself so I don't mind taking the time to do it now. I rarely use anything but a straight or a zig zag stitch so why invest in something I won't use and probably wouldn't like.
It gives me a lot of satisfaction to sit and piece a quilt on a treadle that was made 115 years ago.
If someone wants to give me a fancy machine that has almost perfect tension and sews a variety of stitches I wouldn't refuse it - but I wouldn't consider buying one.
