Oh, you are so not alone! Last week I discovered that I had not been threading the machine correctly to wind the bobbin. I have only had the machine for 10 years! Granted it does wind the bobbin tighter and sews like a dream now.
I will also confess that I broke down and cried last week because I could not get the darn 1/4" seam just right. I bought a 1/4" pressure foot and would you believe it is w o n d e r f u l !! Also treated myself to a rotating cutting mat, a small rotary cutter for convenience, and a brand new ergonomic seam ripper. I feel better now
