The paper in the little bonus swatch charts in the Palette Pastels isn’t receptive enough to the pastels. So, I suggest you use them for the bonus art on the back, and download and print these swatch charts! You can do it on the paper of your chosing, and add them into a journal or swatch book too.
Download the Swatch charts to print on your chosen paper!
