Perfect for adding a little color to your bathroom.
First thing to do is measure the length and width of your shower. Not many are the exact same measurements.
Once you have your measuring done, find a piece of fabric you really like that fits your measurements.
(You don't want a really dark fabric because it will be fairly dark when in the shower.)
(You need to remember a curtain liner. If you don't have one your fabric will always be wet and start to get moldy.)
