I have used minkee as the backing for a baby quilt. The main thing to realize about the minkee is that it has a pretty good stretch to it. I ended up sandwiching my quilt backwards to make it work. Meaning, I taped the top, face down on my floor, then laid the minkee face up on top of it to pin it. I tried the normal way with the minkee taped to the floor, but it had too much give because of the stretch. I did not use batting since the minkee has some bulk to it. So, even though the minkee is expensive, I saved by not buying batting. Maybe I came out even money wise.
The Minkee made a great backing for a baby quilt. Hope that helps!
