I had to resurect this thread as I'm doing the same thing! We moved into another house a couple months ago and have decided to decorate the guest bath with a bicycle theme. I've already painted the walls bright yellow and we have lots of bicycle stuff to hang on the wall and we just got the toilet paper holder. But still searching for a shower curtain. Has anyone seen anything lately? My mom does sew so I may get some fabric. I think a big wheel shower curtain would look neat.
