Thanks Trevor,
The first layer of the lime green base mat are simple large sheets from the dollar store.
I don’t recommend them though.
They are prone to warping with the slightest moisture or change in temperature, and are just not made from quality paper stock...definitely good for quick throw away projects, but never again for a long term layout.
The second layer is cut out foam sheets from Michaels, to add color and depth, but also to hide as many of the seams between the sheets of the first layer.
