I decided on an evergreen and navy blue "feather" pattern for the December page of the calendar. After experimenting with a band application of colors (horizontal stripes), Becca said that it looked like trees, except that it was upside down. I loved the idea so I reversed the pattern, speckled up the sky and feathered away.
The image above is one of my favorites of the day, but the one below is more typical of the forests I made.
Pardon the 180 degree rotation of the photos - the sheets were hanging upside down to drip dry.
