I agree with feline fanatic. Check for lint, and check bobbin tension then if the eyelashes are on the bottom, tighten the top thread. I always sample a small area to the side of the quilt to check tension. I've found it varies depending on what thread I use on the top and in the bottom. I adjust accordingly each time I use the LA.
As I interpert this - flossing the thread in the tension is making sure it is between the two metal disks properly - much like floss is used between teeth!
