I decided that I didn't want to use curtains on our bathroom window so I was trying to find an alternative. I looked at the window films that they sell and didn't like how expensive they were. DIY window film with contact paper!
To get rid of the light that comes through the sides of your curtains, slip one of the curtain ring clips onto the rod bracket. No more side light! Also good when using thermal-backed curtains to help stop drafts.why didn't I think of this?
