Let's face it, when you go to the drugstore or local department store for shower curtain hooks, the affordable option is usually cheap little plastic hooks, which tend to be boring. Why not get creative with the normally blaise task of hanging that curtain? Ideas for hook alternatives really can be "anything goes".
Try threading a sturdy ribbon through the curtains instead of your usual shower curtain hooks.
Metal bangle bracelets make a great alternative, as do old beaded necklaces.
Woven hemp and beads are another alternative.
This option may be a bit more difficult, but it is also more satisfying. Gather some 16-gauge wire, a pair of needle nose pliers, and beads. Cut the wire into the shape of a hook, longer is better in case of error. Bend the hook in half and part the hook at the bottom into 90º making a shoulder for the curtain to hang on. The bottom shoulder then may be decorated and bended with bead and wire work as you see fit.
