Store and Roll Play Mats Without Creases or Damage

Quick answer

Roll your play mat printed side out around a cardboard tube at least 2 inches wide, secure it loosely, and store it upright. That single habit prevents most creases. If a crease already exists, lay the mat printed side up in a warm room for a few hours, or roll it the opposite way for one night, then store it correctly so the wrinkle does not return.

Why creases appear in the first place

Creases are almost never a defect in the mat itself. They come from three habits: folding instead of rolling, rolling too tightly around a thin core, and storing the roll flat under other gear. Mats by Mars mats are printed on heavyweight matte banner material with a slight texture that keeps models from sliding, and that texture is exactly what makes a hard fold so stubborn. A fold compresses the printed surface into a sharp line, and the material remembers it. A tight roll around a pencil-thin core does the same thing on a curve. Storing the roll horizontally under a box of terrain adds a second, flatter crease on top of the first.

Temperature matters as much as technique. Cold material is stiff and holds a set shape; warm material relaxes. A mat that looks permanently ruined after a winter car trip often flattens on its own once it sits in a normal room. Before you try any fix, let the mat reach room temperature rather than forcing it flat while it is cold.

Roll it the right way, every time

Roll with the printed side facing outward. This puts the printed surface under gentle tension instead of compression, so the design does not crack or take a sharp set along the roll. Use a core at least 2 inches in diameter; a shipping tube, a pool noodle, or a rolled piece of foam works. Wider mats need a wider core, because the same bend over a narrow tube is far more aggressive on a 4-foot mat than on a 2-foot one.

Stop rolling before the mat fights back. You want a relaxed spiral, not a tight drum. Secure it with a soft strap or a piece of twine. Rubber bands are the most common cause of edge dents because they bite into the roll and leave marks along the border. If your mat has an overlay option, roll the overlay separately or place it on the outside of the roll so it does not press a seam into the main surface.

Storage that keeps the roll round

Store the roll upright, like a poster, not lying flat. Standing on end spreads the mat's own weight along the roll instead of pressing one side against the floor. Keep it out of direct sun and away from hot cars, radiators, and cold garages. Heat can soften the printed surface, and repeated freeze-thaw cycles make the material stiff and more likely to crack when you unroll it.

Give the mat its own space. A dedicated tube or a corner of a shelf beats a bin where terrain, dice bags, and rulebooks press against it. If you must stack mats, stand them side by side rather than layering them. A mat that is stored correctly for a week will unroll flatter than one that has been folded in a bag for a month, no heat gun required.

Fixes for a crease you already have

Start with the gentlest method: unroll the mat printed side up on a clean, flat surface in a warm room and leave it for a few hours. Weight the corners lightly with books, not heavy boxes, so air can still reach the surface. If the crease persists, reverse-roll it for one night: roll the mat printed side inward around the same wide tube, which pushes the crease the other way. Unroll and check. Most single folds relax after one or two nights of reverse rolling.

Never iron a printed mat directly, and avoid steam. The matte banner material and its printed design are not built for direct heat, and a hot iron can glaze or distort the surface. If a crease survives a week of correct storage and gentle reverse rolling, it is likely a hard fold that has compressed the material itself. At that point, treat the mat as a spare or a travel surface rather than risking damage with aggressive heat.

Crease diagnosis: symptom, cause, and fix

• Sharp line across the middle: This is a fold crease. The mat was folded or rolled around a very thin core, compressing the printed surface into a hard line. Reverse-roll printed side inward for one night, then store printed side out on a core at least 2 inches wide. If the line is still sharp after a week, stop treating it and use the mat as a travel surface.
• Curved ripple along the roll: The mat was rolled too tightly and stored that way. The material has taken a set along the curve rather than a single fold. Unroll printed side up in a warm room for a few hours, then re-roll loosely. This usually relaxes within a day or two.
• Edge dents or bite marks: Rubber bands, zip ties, or a tight strap pressed into the roll and left marks along the border. Switch to a soft strap or twine and store upright. Edge dents are cosmetic and rarely affect play, so no further action is needed.
• Wavy surface that never lies flat: The mat is being stored flat, layered under other gear, or kept in a hot or cold space that keeps resetting the material. Move it to upright storage in a temperature-stable room. If the mat is still wavy after two weeks of correct storage, the storage environment, not the mat, is the problem.

What this means for Mats by Mars mats

• Mats by Mars: Final Frontier Tabletop Wargaming Space Play Mat: Mats by Mars mats are printed on ultra-durable heavyweight matte banner material with a scratch-resistant, vibrant design, and the space design suits X-wing, Attack Wing, Rogue Trader, and other futuristic combat. The heavy banner material is tough enough for repeated rolling, but the matte print is the part you are protecting. Printed side out keeps that surface from creasing against the core.
• Mats by Mars: Noxious Sewer Tabletop Wargaming Play Mat: Each mat features a slight texture that keeps models from unwanted sliding and is wet-erase compatible and easy to clean. That texture is why a hard fold is so visible and stubborn. Rolling loosely preserves the grip surface, and the wet-erase finish means you can wipe the mat clean before storing it instead of trapping grit in the roll.
• Mats by Mars: Quinfinity Sapphire Tabletop Wargaming Play Mat: Quinfinity Sapphire is a blue quintuplet city design built for the Infinity sci-fi miniature game, with size and overlay options available. If you use an overlay, roll it separately from the main mat so the overlay edge does not press a line into the city surface during storage.
