I would highly recommend the hotel style shower curtain rings with ball bearings on them that make it easy to slide. You'll need to put button holes in at the top and also use a clear plastic shower curtain liner which you can pick up anywhere. Here's a link to the curtain rings you can find at Bed Bath and Beyond: https://www.bedbathandbeyond.com/store/product/hotel-collection-roller-ball-shower-curtain-rings-in-chrome-set-of-12/1010518628

The grommet kit with rings will be much more secure when you pull your shower curtain back and forth. I like the idea of the ball bearing ones - classic and slide well.
