Sounds like the top thread was pulled too far to the back instead of in the sandwich. This is a tension problem. Either you need to increase the top tension, so the thread isn't pulled down as far or or loosen the bottom tension a bit so it goes up a bit. If it is just a little (like the botton thread runs flat with almost tight loops along it) when you wash the quilt, the batting will plump and it should be alright. If you have actual "eye lashes" you may need to fix it.
