Minky for quilt backings
For those of you who have used Minky for quilt backings I have a few questions. Currently making two quilts for my grand-daughters (ages 6 months and 5 years) and have thought about using it as these will be used on the floor for playtime mostly. How difficult is it to quilt through? Can you use it on a quilting frame (Grace) or will that stretch it? What batting works best (they live in Colorado). Is there a certain thread or needle to use with it? Any other tips or suggestions you can give me? Thank you everyone!
