I've made 2 with minky as the backing ( not the binding). The first one, I used regular 80/20 batting. It is too heavy, in my opinion.
The second one, I used bamboo batting. It is our favorite quilt, the one everyone fights over while sitting on the couch. It is the perfect weight, not too heavy, and not too thin. It has body, without the weight. We love it.
For all my future minky quilts, I will only use bamboo.
