Such a beautiful collection of colors! I can't wait to try them out!!
You will also need a water brush. They are available in small and medium.
Tina Aszmus shared a tutorial on how to use these watercolor papers on the Studio Calico blog here. It looks like they will be perfect for making fun backgrounds or coloring in stamp images. Just what I've been wanting to try, but now I don't have to figure out which paints to buy and find space to store them!
