I do believe that it has been a "month of Sundays" since I've done a card based on a sketch from the Card Patterns blog. How long is that precisely? A "month of Sundays" is longer than "a blue moon" but considerably shorter than "a coon's age" (hope that clears up any confusion, LOL).
The butterfly from SU!'s retired Natural Beauty stamp set is a favorite of mine and is colored with Copic markers and layered onto Curio patterned paper from Basic Grey.
