I just bought a Singer 4423 because the price was right for my grad-student budget. I learned to sew on my mom’s Singer that was 20 years old when I used it, and it’s still going strong! Thought I would buy one for myself, thinking that the brand was probably reliable.
I’m questioning that now because I’ve used the machine for about an hour and a half and I can’t get the straight stitch to actually stay straight. I read other forums, which suggested a number of fixes, including using a sharper needle, changing the thread, adjusting the tension, making sure the needle is centered, assuring that the stitch selector wasn’t on zigzag, and checking the stitch width. I’ve tried all of those things (except different needles because I was sewing at about midnight last night), and I still have the same problem:
The stitches periodically jog to the left, making a jagged stitch line. The bottom thread looks more crooked than the top. I am sewing on canvas and duck. Any recommendations? Thank you for the help!!!
