Here is the shower curtain I made for my DDIL, who picked out the fabrics and designed it. I used french seams to enclosed the raw edges, but a serger would work great. My DS wanted a "window" of vinyl at the top and I found an inexpensive clear vinyl with embossed bubbles that I cut up for the window. Either sew with the vinyl between two layers of fabric or use tissue paper between the vinyl and your presser foot, or it sticks and the machine won't advance the fabric. Here it is: (looks like pillowcases sewn together on the bed, but looks much better hanging LOL) I used buttonholes for the curtain rings. They use a clear liner behind it so as to not block the light coming through the "window". Works great!
