Wreaths are a lovely addition to an exterior door, but not all doors are designed to hold nails or screws. Some include a window and would not look right when adorned by a stick-on hanger, and others are made of metal. In any case, it is best to find no-hole ways to hang a wreath, especially on a steel door. Use one of the following options instead of causing damage while trying to enhance the entryway of your home. These are inexpensive and easy options that will securely hold your decor.
Use an Upside Down Peel-and-Stick Hook Trick
A hook detracts from the appearance of a beautiful wreath. Instead of using a peel-and-stick hanger to hold a wreath on the exterior of your metal door, place the hook on the inside instead. Mount the self-adhesive hook upside down near the top center of the inside. Tie a coordinating ribbon or a piece of narrow jute twine to the wreath, and tie a sturdy loop. Place the loop over the top of the door and around the overturned hook on the inside. As long as the hanger remains in place and the knot does not come undone, the wreath will also stay put. To keep it from shifting as the door opens and closes, apply a little poster putty to the back, and press it firmly into place. The poster putty will come right off when it is time for something new.
Line an Over-the-Door Hook with Peel-and-Stick Craft Foam
Over-the-door hooks are commonly used to hold wreaths. They are fantastic no-drill options, but those made of plastic are not durable or completely adjustable. Metal varieties can be made to fit, but they will scratch. Simply opening and closing the door will cause the hanger to shift, and the damage can be deep and irreparable. If you decide to use an over-the-door hook to display a wreath, line it with peel-and-stick craft foam first. It comes in various thicknesses. Choose a size that will fill in the gap between the hook and the door. It will hold the hardware firmly in place.
Use Duct Tape to Attach a Ribbon or Jute Twine to the Top Edge
It is said that if duct tape will not hold something together, the item is irreparable. In many cases it is true. It is often the best no-drill option for hanging all sorts of things. Best of all, it will not be seen. Tie a ribbon or jute twine to your wreath. With help from another pair of hands, duct tape the ribbon to the top edge of the metal door. Make sure the surface is clean or the tape will not stick. It is thin enough to allow the door to easily open and close, and it is strong enough to hold the ribbon or twine. If the edges will show, use colored duct tape. It will blend right it while securely and beautifully holding a wreath of your choice.
