@CCatMan I appreciate the advice. So this kind of answers one of my questions. I wondered if I take a painter’s drop cloth in matching dimensions to the curtain and attach it, would that be much different than if I double the size of the drop cloth and attach it with deliberate folds (like pleated pants). What you said somewhat implies that It would help to use double the size of drop cloth and force some deliberate folds which would create an air gap with the curtain.
