Hi: I have made a few things using minkee and have used my walking foot. I just finished a couple of 12" baby blankies using flannel backed satin and minkee. They sewed up beautifully. I also made an Olivia the Pig quilt for my gd Olivia and backed it with minkee and used batting in between. I did not have a problem with it. I have sewn with the minkee on top and on the bottom and it did not make any difference. I did make sure that I pinned it well.
