I have learned a few tricks over the years on how to maximize your customizing time, especially when working on more than one custom at once. I don’t get much time for customizing these days, so I try to get the most out of the time I have. One of the ways in which I do this is something I like to call the One Brush Method.
I think the best way to explain it would be to give an example. Before I start painting, I line up my figures according to the colors I will be painting them. My first figure needs some pieces painted white. I add a drop of white paint to my paint tray, paint it, and move on to my next figure, which needs some light yellow pieces. I add a drop of yellow to the pool of white paint, and keep painting. The third figure needs orange, so I only need to add a drop of red to my mixing pool. After this figure comes flesh color (more white, tiny touch of black), brown (more red and black plus some green), and tan (more white).
During this entire time, I haven’t needed to wash my brush once, because I keep adding to the original color on the brush. This has definitely saved me some time. Also, keeping a pool of paint that is constantly wet also saves me time. If I hadn’t taken a few seconds to line up my figures in the beginning, I would have had to mix several pools of paint instead of just one. This can also be a waste of money, since you don’t always use all of the paint you mix.
I use a medium size brush for this, but at times I will also grab a second smaller brush for detail work with the current color. This second brush will get set aside when finished, and washed later. I still use my main brush to continue to mix colors and save time.
It might not sounds like it would save you a lot of time, but when you are working on five or six customs at once, like I always am, it can be a huge help.
