What is the best way to hang wreaths on your outside windows?
The way I do it is to take thin green craft wire and loop it around the wreath and then run it up to the top of the window, then down the inside to the lock for the window and tie it to the lock. That way you don,t have to put any holes in your windows and no nails are necessary.
Reply:3-M has been making hooks for interior use that you can remove without any damage after you're done with it. - apparently the now make green hooks specifically for wreaths. They're available at most hardware stores and BedBathBeyonds
