I am on a roll with end of year teacher thank you cards. Here's my second design, using really old patterned paper (it came in my consultant kit when I signed up for CTMH in 2008!) and a sketch from Atlantic Hearts Sketch Challenges. I took some liberties with the sketch by tilting the skinny pieces and adding a circle, but hopefully you can still see it's the same sketch.
