Wow are you me!!! I had the same problem yesterday. My 301 was totally rehabed and working great, then yesterday I figured I could use to do my paper piecing...wound bobbin and stitches were off on the botton...so loose...Tried redoing bobbin same problem, tension same...Guess I'll start from scratch today and see what happens...Must be something with the bobbin and the way were putting it in...
