I am posting a picture of the 'rig' I created to mix washes
You can see at the top I have some oil paints, at the bottom I put a 'squirt' of thinner. Using a brush (one of the two styles) I pull dow the paint into the thinner.

That's a pretty neat setup Scott.
Thanks for sharing.

Slodder,

What are the benefits of your method over "normal" methods?

I can see that it will allow you to make the wash stronger as and when you need to, but I'm a newbie so humour me

The other methods I have used are a 'flat' palette and the advantage here is you can have a larger quantity and mix and add more color as needed quite a bit easier. The liquid is concentrated at the bottom.

The other method I have used is to use a soda bottle cap as a mixing receptical. This method is easier to get the color into the thinner and to 'see' the color.

I also like this because it spans the entire concentration of color, at the bottom you get the thinnest color, as you move up you get more and more thicker and thicker color right on up to the full oil paint.

I can quickly and easily dab in the middle and load my brush with the same color as I'm washing and add that to the model if necessary.

These are all subjective and my preferences so by all means if you're comfortable with a different way use that way and don't force yourself into something else.

I normally use an epoxy mixing up and then apply with a syringe.....

Neat idea Scott!
I've found for my needs, I use an old glass spice jar and add my oils (artist) and thinner, and make a couple bottles of different coloured washes, all I need to do is mix it up, and away I go.
