… but, if we're being honest, it would be more useful to me if the WarhammerTV Tip Of The Day video thumbnails had pictures of the things being painted.
That having been said those videos are really helpful. One of the problems with printed painting guides is that they can't show you how to apply the paint. Games Workshop painting guides are especially bad for this since they describe about three different painting techniques as “layering”. Sometimes, especially when your eyesight isn't that good as in my case, it can be hard to tell if some of the more subtle differences in colour are actually layering or highlighting.
With a video, however, you can literally see how the paint is applied. I'm one of those people who learns best by watching and imitating. The most useful thing to me has actually been having a clear visual example of how much to thin my paints by and confirmation that the awful first coats I'd achieve were meant to look like that.
That last one was actually quite affirming. It also helps that I now have this enormous open source recipe book for painting methods even if Duncan Rhodes' face makes it a little hard to find that I'm looking for.
