I've made a lot of quilts with Minky on the back. Every time someone asks for one I groan because I don't like working with it, but the results are always great. Here's what I do. I lay the minky on the ground and measure batting and my quilt top to make sure I have enough of everything. I use Elmer's washable school glue to glue the batting to the minky and then I glue the top to the batting. let it dry for a day. I have a quilt sandwich with cotton, batting and minky to check the tension. I quilt with the minky on the bottom and use Machingers and quilt like I do any other quilt. Try to ensure that the quilt isn't hanging off the sides of the table. The drag can really mess up your FMQing. Good luck and have fun!
