i love using minkee fabrics for the back of quilts...did the first one 5 years ago.
the kids call them the 'get-naked' blankets because they are so amazingly soft!. they quilt beautifully. the only things to think about are:
1) the edges (after being cut) are -messy- take it outside & give a good shake before using.
2) there is a stretch. make sure you smooth the fabric, but don't stretch it.
3)the (wrong-side) is kind of slippery. i used batting in mine but some people don't like them that warm...heavy.
i found the batting just helped hold everything (plus added extra weight/warmth) but any fusable interfacing could be used, or flannel...or really you do not have to use anything if you would like it to be more lightweight.
4) once you make one...everyone is going to be asking why theirs doesn't have that backing....but it is expensive!
