As an aside, I have been considering getting a 'wet palette' for my acrylics. A friend suggested 'Redgrass' but I can't find a source in the UK. I could buy from Europe, but with the current crisis I'm trying to source within the UK if possible, .
Therefore, can anyone recommend any other brands?
I just started using a wet palette but I didn’t buy I made my own. Take any airtight container, fold paper towel over a few times (about 4-5 layers) until you get a spongey surface. Wet this spongy paper towel until it is fairly damp but not soaked. Then place parchment paper on top of this wet “sponge”. When done painting seal it up and paints can stay fluid for around a week this way. When switching projects or if the parchments gets too dirty/full of paint, pull it out and toss it and put a new piece down. Recharge and replace the spongey paper towel layer as required
