Hmmmm..
Would the dense styro meat trays work??? I'm washing and saving all ours for future scenery construction (bulkheads for hills and mountains etc.) I don't know if they'd be thin enough... I'll experiment and let you know...one would razor them into strips, and very thinly and faintly score to simulate joints,though I doubt you can actually see side walk cracks from, oh, 300 feet up (my wild guess of the scale) without binocculars!! then paint appropriate shade of grey, dull coat finish if you use reg. artist acrylic...but a flat latex should work....I hate to buy something if there's a recyled material that can be made to work!!!
