I made one for my DD. I bought the vinyl coated cotton fabric. I made two curtains, one for vinyl facing out and one for the vinyl to face the stall side. I hemmed them and made eyelets for the curtain rings. I didn't piece it, just hemmed the fabric. It was the color and design she wanted that she couldn't find in a regular shower curtain. You could use the vinyl fabric for the lining. It's soft and supple and sews like cotton.
