4. Hang art without a single hole in the wall
Blank walls are what make a rented room feel temporary. Most tenancy agreements prohibit nails, and many tenants therefore hang nothing for years.
Removable adhesive strips solve it for anything up to about 7 lb or 3 kg per pair, which covers most framed prints at A3 size and below. The failure rate is high when people rush, and almost zero when they do three things: clean the wall with rubbing alcohol and let it dry fully, press each strip firmly for thirty seconds, and wait an hour before hanging the frame. Do not use them on wallpaper, textured or freshly painted walls, where they take the surface with them.
For heavier pieces, lean rather than hang. A large framed print or mirror leaning on a shelf, a mantelpiece or the floor against a wall reads as intentional and carries any weight you like. A narrow picture ledge fixed with two screws is worth asking permission for — most landlords say yes to two small holes, and a ledge lets you change the display constantly without more fixings.
Plan the layout on the floor first. Cut paper rectangles the size of each frame, tape them to the wall and live with the arrangement for a day. Keep 2 to 3 inches between frames in a group, and hang the centre of the arrangement at eye level, around 57 to 60 inches from the floor.
When you move out, remove strips by pulling the tab slowly straight down along the wall, never outward. Pulled correctly they leave nothing; pulled outward they take paint.
Other no-hole options worth knowing: tension rods in an alcove for hanging plants or a curtain, washi tape for a gallery of unframed prints, and freestanding easels for large canvases.
