It’s like the thickness of a sandwich baggie.

This is NOT lavender. It is a light gray color. Very disappointed!!! I paid the higher price for the pretty color… This is a cheap 7.00 liner that I paid 15.00 for.

perfect fit

Good quality, but to be clear it is 84″ LONG and 72″ WIDE. I was looking for the reverse dimensions.
