I purchased a shower curtain but never ended up using it for that purpose, instead I cut it up for the outside of a beach bag, handles and pocket, the liner is outdoor fabric left over that I had laying about. . size 20x20 - perfect for 2 towels and bathing suits. No batting needed, which is good since it will get wet. Nice and light weight. Next time I buy a new fabric curtain I will just throw the old one in the washer and then create a new bag ; )
