Just a reminder to thin your paints and a tip for how to do it:
This is a homemade wet palette made from a lid, a thick wiping cloth and some regular greaseproof paper. Soak the cloth in water, and fill the lid. Place the paper over the cloth and put your paint on the paper. That way the paint will keep from drying much longer, if you want it to be even more diluted you can poke some holes in the paper with a needle.
I usually mix the paint 50/50 with water.
