When your party guests visit your bathroom they will get a fright with the shadows lurking behind the shower curtain, just like Psycho.
What you need
Clear Plastic Shower Curtain or semi transparent plastic curtain
Take your shower curtain and lay it down onto a table and secure with sticky tape so you can work on it without it moving.
Paint the silhouette of a ghost or if you are a little more creative a witch, cat or a scene from Psycho onto one side of it.
Then let it dry and hang on to your shower.
This is not intended to be used in the shower as it’s not water proof paint.
If you want to use it then use a plastic paint or spray paint obtained from your hardware store.
