Post-its are great for rearranging priorities, for adding and subtracting from your idea/goal folder. As soon as I open my folder, I see the art and writing projects I want to tackle first or remember a promotional idea, etc. There are so many colors and style of Post-it's, you'll easily be able to find what works for you.
If you’re like me , you have these items in your studio already or can use whatcha got on hand to do the job. Get as fancy as you like, or keep it simple. Here is how I made mine. http://katmcdart.blogspot.com/
