Wet Palette - Final Form?

A symptom of the problem.

(Please excuse the even less good than normal pictures. I changed the settings on my camera and now I don't know what's happening anymore.)

I've tried to make my own wet palette before, but failed miserably for reasons to be revealed in a BONUS HOT TIP below. This year I mostly have been using the P3 wet palette. It's the first functioning wet palette I've ever used. It's got a bad rap, but at least it kinda works.

The bad rap goes as follows:

1. The box doesn't seal, such that the water inside all evaporates while you aren't looking, or even if you are.
2. The sponge that comes with it doesn't absorb very much water, or pass it to the palette paper very well.
3. The supplied palette paper is too easily permeable for miniature paints (it works very well for heavy body artists acrylics, apparently)

I live in cold, damp Scotland, which might have contributed to the first too flaws not bothering me. The last did, however. Water is supposed to gently osmose up through the paper in a wet palette, keeping the pain from drying out. On the P3 palette, all paint is immediately diluted to a thin glaze, then it gently oozes across the surface and makes friends with all the other colours. Oh, and I'd add my very own 4:

1. There's not very much surface area to work with.

Blogger won't let me make that a 4.

Behold!

Inspired by articles at Arcane Paintworks and Lil'Legend I had a crack at making something better.

It's a combination of the Lil'Legend jay-cloth-wrapped sponge, and the Arcane Paintworks tupperware and leetle bit of washing up liquid to stop it going mouldy.

Let's see how it works!

I sprayed too much white on the backpack, and the heid is supposed to have a nice blue gradient, but I forgot.

And fixed!

It worked pretty well! I could control the consistency of the paint! I could put blobs of paint near each other and they didn't immediately mate! The paint is still both wet and where I put it, nearly a full day later!

We'll see if it goes mouldy later, but it's good so far.

BONUS HOT TIP: Morrison's own brand baking paper works well for this purpose. Previous attempts with Sainsbury's equivalent didn't work at all, because it is silicone coated and completely waterproof.
