thank you Julia, over the years I've used everything on the market, but this query was about specific poly batt. I know there are lots of good brands, we are very fortunate needlepuch and scrim has been added to make them user friendly. I have one batting in my cupboard that actually says on the packaging 1/4" to 1/2" distance
Like that is going to happen these days, but it will be fine for a regular quilted wall quilt that will never be washed.
