I probably just reinvented the wheel, but here goes. I'm just beginning the scratchbuilding business.
I built this structure from balsa wood, but wanted it to be brick. Adobe Illustrator has a brick texture as a standard feature. I filled a rectangle with the texture, imported it to Photoshop and printed it on inkjet photo paper at a reduced size (to make the bricks the right size). I had to do the Photoshop import because I haven't figured out how to make Illlustrator reduce the size of the bricks.
A spray with Dullcote keeps it from being shiny.
Now, if I can find a stone texture....
