There is always a way to be creative. This is one of my portable watercolor palettes. I cut a page protector to the size I wanted, punched holes to fit the binder and dabbed watercolor blobs inside the 2 layers. I then made a cheat sheet to sit behind the colors. It makes me happy to see this when I open my book. The binder is a Levenger Circa Softolio. I make my own planner pages and add mixed media paper for creativity.
