If you took W n N or W n W then your quilter loaded it upside down if you have batting fuzz on the quilt. I use one of the older brush lint removers and this does a really good job at removing that lint.
Your rule of thumb on any type of cotton or cotton blend batt is the bumpy side goes UP, slick or smooth side goes to the backing fabric.
This info is provided to you by a longarm quilter.
