Well, I went & bought some paints of my very own (finally). This is the result of my first try at painting at home unsupervised.
I set 2 challenges for myself this time out: a half & half style paint job, and blending colours to get a specific green. I bit off a little more than I could chew, and I still haven't quite achieved the green I'm after, but I'm a little wiser than I was before.
I think I've also decided against going with the half & half paint job.
