Yup... It is plywood (with a vaneer finish), here is the leftover from which I cut out the test piece... I painted over the edges, which is why it might look different in my original picture. I did paint it. I used "Craft Smart" acrylic paint that I picked up a Micheal's (a craft store near my house). I used the following colours: Golden Brown Mustard Yellow Expresso (I thinned this down until it was a wash) Dark Yellow Ivory Each bottle costs just over $1 CAD and has a volume of 59ml. I love this paint for terrain building because I most definitely don't want to waste my expensive hobby paints. That is a great idea. This was just a test piece, it isn't meant to be terrain at all. I just wanted to see what effect I could achieve without wasting too many materials. I also wanted a a chance to give my new yellow paints a try. I think your hill/dune idea would look really good. Thanks for the comments! Thank you! Feel free to post your picture. I'd love to see what it looks like using a different colour scheme.
