Wet Palette Question

[Malebolgia]

Honestly, I think wet palettes are only nice to use during single paint sessions. Afterwards the colours get weird, the paint starts to act weird and it just doesn't work well. But for single paint sessions (up to several hours) they are great. Good for blending, smooth coats, colour mixing, etc.

Just and update on this. I tried the parchment paper and it has worked out really well.  The paint has stayed wet but hasn't turned into a muddy mess.  The sponge is still damp as well.  I think the parchment paper is a keeper for now.
