Old West Cactus Basing

I didn't get the cactus bases painted today but I have blended them in with a mix of wall filler, PVA glue and sand, followed by a sprinkling of model railway ballast to add a bit of texture. I'll sand them down a bit tomorrow when they have completely dried then basecoat the whole lot in a desert khaki shade to match my other terrain, ready for some washing and dry brushing. I think they will look pretty good, especially if I also add some tufts and weeds around the bases.
