bought this for 90 cents

might be useful for mixing acrylic paint for woodgrain finishes and the middle section for decals--must remember to not use lacquer thinner with it, though

I got 2 very similar ones in Smiths over here Alan. Used mainly for acrylics but I have used Gunze Mr Colour and their propriety thinner in it without a problem. Cost a little more then 90 cents Aus though

I have several of those palettes; they're great! One tip to keep them clean - wrap them in aluminum foil (press the foil gently into the depressions) then mix the paint in them. When you're done, remove the foil and throw it in the recycling bin. I'll occasionally get a break in the foil, but it's a lot easier to clean. Without the foil, even acrylics will eventually get permanently stuck to this plastic.

Now here's me thinking about Dalek Saucers....

Those are handy. I went through a ton of them back in art school.

I was able to get ones made of aluminium at the time. No idea if can still get the metal ones, but they could save you a bit of money on foil lining the plastic ones and laquer thinner wouldn't be an issue with them.
