Almost a year ago i invested in a few "transparent tablecloths" (or tablecloth covers) to use as covers for my boards during play. Long story short, they work well with Onus playmats. The playmats are of fine quality, and are certainly durable, but placing them under a thin clear cover reduces wear and tear to essentially zero. Here are a couple pictures showing one of the mats with a transparent tablecloth on top of it:
Note the glare - that's the cover. In practice glare is not a problem when the area is viewed from above or a normal sitting position.
With one edge of the transparent cover folded up, to give an idea of how flexible and transparent the cover is:
Such tablecloths/covers come in a variety of sizes, but these are the ones i have:
Mine are 140x100cm, and cutting them in half provides a good cover size for most typical game boards (they're not large enough for a fully-decked-out Talisman set with all expansion boards, but an uncut sheet is).
That is a good idea. For reference I am playing my first game "as the designers intended" with unsleeved cards and the naked playmat and it is working mostly great. That playmate is slick! (That is old USA slang for really good as well as descriptive of the cards sliding easily.)
Unfortunately for me I am going to have to sleeve the cards - I have some nerve damage and I have a hard time handling things like cards (and books, magazines, etc.) and I am going to destroy them if I do not. I have already sleeved the Event/Order cards (Mayday 45 x 68mm - the blue/teal pack) but have not found a perfect fit for the unit cards.
Just chiming in with feedback - The playmate works great so far! I am the problem.
