I noticed last week when I was working on piecing the strips, that every once in awhile the upper thread would break. (bobbin thread was fine).
I also noticed that it almost sounds like it is stitching through paper... a sort of tick tick sound when stitching.
It doesn't jam or snag, or snarl, just every once in awhile the thread breaks.
Any suggestions? Please help, new to sewing and not sure what is happening.
