Ooh, sounds like a plan. I have no access whatsoever to a Games Workshop usually, but I’m heading up to the big city in a week or two and I’ll be able to try something out. I do really like the look of the texture paints, and I’m totally gonna try out some models with that. 
But, more than anything, I’ve really learned a lot about using Green Stuff (or some weird white Japanese equivalent of it, anyways). Nurgly blobs are easy to craft and learn from ^__^
