Every so often I have to take the time to replenish the paint in my palettes. I use one for the classes I teach and keep one in my studio for my own painting. I try to make the job a little easier by keeping all my tubes of paint, a color chart and a list of the colors I currently have in each palette together. Then, it is just a matter of opening up tubes, squeezing out fresh paint and patting them smooth in each of the paint wells. A messy job but so nice to have clean, fresh watercolors!
