i just finished quilting a t-shirt quilt for a customer who used minkie for the backing- we also used batting- it quilted up beautifully! it is a heavy quilt= but will be oh so warm & cozy! I did not have any problems with it- her t-shirt blocks had stabilizer- the sashing strips and corner stones did not and were flannel- the minkie backing was one of the long-nap ones- I am careful to smooth but not stretch the minkie- but have been backing quilts and quilting other's quilts with it for 7 or 8 years now- I've never really had any problems with it- it quilts up beautifully. I do use a longer stitch length and loosen the tension on top a little bit-but that is the only adjustments I make.
