are the eyelashes everywhere, or just on the curves? If everywhere, make sure your presser foot is down. My Viking has a special setting if I use my hopping foot. If you are using the hopping foot (one with the spring) then check your manual and see if that model has a special setting too. If the presser foot is down, and you aren't using the spring foot, try tightening your upper tension. If the eyelashes are just on the curves, you need to slow down.
