I ordered Genevieve Crabe's zendala stencils. Love them - they are quite easy to use and like the snowflake method - connect the dots however you wish.
I had been seeing some color creations done on gray-toned paper and decided to try that. I was not very pleased - the gray turned my yellow green, and it became "dark". SO I had to go heavy with white highlights. No mistakes - only opportunity, right?
