Housemartin has pulled one last con on me; he needs a place for those chariots (with the "oh-so-lovely" charioteers) to run their races. He sort of left that lying there and, being the twit that I am, I said that it would be dead easy to make a spina and then paint a track based on the board that he showed me. Thus I find myself painting a terrain mat to match the track that his boardgame came with. For all my complaining it is a simple matter as you can see below.
a 6" by 30" space in the center for the spina and a series of 4" wide pathways around it,
the first layer is in a darker shade, a lighter shade will highlight the track
three more lanes around the first and it is time to wait for it to dry,
notice how I cleverly left a tiny gap of the base color between the lanes
I can't find my copy of Ben-Hur so I will be forced to undertake some actual research into exactly what a spina looked like. I remember statues and an obelisk and something involving dolphins....
