cjhp I have had much success with wreaths on my double-hung windows by using one finishing nail which is tapped into the center of the frame above the window and then tying a big loop of fishing line or even dental floss around the wreath and just hanging it from the nail. The nails stay in place from year to year and are not noticeable at all. Good luck!
matthew5 Talk about a mold magnet when it rains. This looks like something you'd use for a parade of homes, a wkend or two, but not during the entire holiday season.
