This is the best idea I've seen in a while. Who wants to see your sticky notes of to-do lists all over the refrigerator? Spruce up an old window and use a dry-erase marker to keep track of your lists - grocery lists, to do lists, reminders, notes to your honey. Windows can easily be painted with acrylic paints, or use a decal as in this picture. I'm thinking there are plenty of you creative people out there to make windows that are ten times as cute as this one.
Also, I'm in love with those bird hooks! I'm searching for some, so if you know where I could find them, I'd appreciate the tip.
