I recently tried out a wet palette for the first time. If you use Vallejo, P3 AP or any other paint that comes in drop bottles, you owe it to yourself to try it too. A quick google will give you illustrated guides, youtube tutorials and everything you could possibly need, but just in case, I'll show you how I made mine.
It really is dead simple. Get a flat plastic box with a lid. I used one from the supermarket that is for keeping pre-sliced sausage and such.
Stick a piece of wet paper towel on the bottom. Cut a piece of parchment paper to fit in the box and place it on the wet paper towel. Done.
You can now drip paint on the parchment paper surface just as you would on your regular palette, china plate, CD or whatever you normally use. The difference is, the paint won't dry! To try it out, I deposited the above blotch of paint at about 1900 yesterday and painted a gang of German soldiers. I then put the lidon beforeI went away and watched a documentary and the evening news. When I came back at 2205 the paint was still wet and I could use it to fix the parts I had missed during the first paint session. If you are lucky enough to get hours-long paint sessions, or if you only paint in short bursts, this is ideal.
