This stuff was great! Came precut to my pool size. It was just a little big, just trimmed that off and tossed it. Would rather it be a little big than to small. It was a thick felt material. I've read some reviews that it was a thin felt. Mine was not. It was very thick, almost like a blanket. Made my pool bottom super smooth and helped with ease of getting all the wrinkles out of the liner.
