Well, concrete and Tarmac actually. Two new products have been added to Spinneyhead Scale. The idea is simple enough. Model railway builders need to create surfaces for their roads. They could paint them or they could buy some of the specially printed sheets that are available, which would get expensive for a large surface. Now there’s another option. Buy these files and print as much road as you require. Supplementary images- road markings etc. will be coming along at some point, and I may have some physical products to add later today.
