I made one quilt with minky backing and I made the mistake of spray basting it to keep it from shifting so much while I was quilting.
Minky is polyester and apparently of a type that reacts with the basting spray, causing the needle to gum up and require cleaning every couple of minutes.
Ack! I thought I would lose my mind!
I had constant skipped stitches and tension problems because of the sticky needle and thread.
I also had a heck of time with the Minky resisting being moved - wherever I was pushing on it, trying to slide it around under the needle, it was gripping the cabinet surface. I got a giant poly bag - very thin and crinkly, not the soft clear plastic that comes from the dry cleaner's - and covered the surface with that and that helped. My all-cotton quilts just glide right over the cabinet and cutting table mat that's behind the cabinet - I'd never had any trouble with that before.
There was much wailing and sweating here, trying to get that Minky thing quilted. Thank God it was a rather smallish quilt, not my usual queen/king. I used to say that I would NEVER do that, again, but now I say that
if I were to try it again, I would not use basting spray.
In fact, I would probably tie or bar tack any quilt with Minky on it in the future. Good luck and have fun with your project!
