The poster should do all the talking. Everything else gets in the way.
So: neodymium magnets at the top two corners, string down the sides, done. No frame, no box, no visible support. Just the image, held by almost nothing, floating on the wall.
The magnets are hidden behind the poster. The strings vanish against the wall. What’s left is pure content — maximum impact, zero distraction.
The system
Materials
Neodymium disc magnets (N52, approximately 12mm diameter, 3-5mm thick). Two for the wall, two for the poster back. String or thin wire that matches your wall color. Cotton, linen, or nearly-invisible nylon fishing line all work.
How it works
Two magnets mount on the wall, positioned at the top corners of your poster width. Matching magnets attach to the back of the poster at those same corners—friction holds them flush against the wall. String runs down each side from the poster’s back edge to an anchor point: a small hook, weight, or the baseboard. The string prevents rotation and sway. That’s the whole system.
Mount. Slide. Done. Change posters in 30 seconds. No tools, no damage, no visible support.
The frame disappears so the poster doesn’t have to.
