Kathy, I guess ignorance is bliss. I have used the minkie on two baby quilts. I machine quilted both of them with no problem! They turned out lovely. My machine did have a lot of minkie lint to clean up afterwards though!
The only "real problem" I found with the minkie is that the pieced top of the quilt gets put face down on the floor because the minkie is so soft for the baby to lie on. :D
