I have used Minkee on two quilts. I loaded the minkee with selveges pinned to the leaders. When loading the minkee onto the rollers I was very careful not to stretch the minkee. Also I used polyester thread for quilting. I tried using cotton but kept getting large loops on top and bottom of quilt. I used a size 18 needle and stitched slowly. I kept the quilt a bit loose on the frame while quilting so the backing would not stretch.
I would like to use it again on a quilt but just not too sure I will. Quilting with Minkee fabric is a lot like trying to quilt MARSHMALLOW FLUFF.
But it does look really good when finished.
