Hi everyone!
I was sewing along fine, until I had to fill my bobbin... Now loops on top of fabric, thread's so loose it can be almost pulled out.
It's a fairly new machine to me - Brother CS6000i. Looking thru the booklet, it states to adjust upper tension. I did it tighter, didn't help. Did it looser, didn't help.
I changed the needle, rewound the bobbin 3 times, and put on a new spool of thread...
I hope my pictures attach...
Thank you for any help!
Diana
