When I have eyelashes on the back of a quilt, after checking the bobbin tension and that the machine is threaded correctly, here's what I do on a practice sandwich:
1) Turn the top tension to it's lowest setting, start sewing, check the results - which I expect to be bad at that point.
2) Adjust the top tension to the next higher setting (1/2 turn on my HQ16), sew a bit, check results. If top tension is your problem, the eyelashes should be somewhat smaller.
3) Continue doing (2) until the tension is even/the eyelashes no longer happen while quilting.
This seems to work well for me.
Good luck.
