The mystery playmat can be 24"x14" or 28"x14" and can come with either stitched or unstitched edges. Beyond that, we can’t reveal much else. The artwork, color, and style of the mat will remain a mystery...until it arrives in your mailbox after you’ve ordered it. By purchasing a mystery playmat, you agree to let us choose any playmat design at random and send it to you. We source playmat designs from many talented artists, as well as some that our designers have created just for you.
