Have you ever used Stablio Woodies? They are a great water based crayon pencil. OMG! I love using them. They can be opaque if you use them heavily or they can be transparent, too. You can see it used in many of the cards in this series but the third one above shows up really well. It is all the red that you see with the exception of the lettering. If you do not have these Stablio pencil crayons I highly suggest that you get them. They are such a good way of adding color. I usually use them as one of my final additions to a mixed media piece.
