A month or so ago we did some ice cube painting on blank note cards as an afternoon project. At the time it happened to be the only white cardstock I had in the house but as an after thought I figured they would be perfect Thank You cards.
Boy was I right, I love how they came out! As an added bonus Maddie wrote 'Thank You' on a piece of paper that I scanned into the computer. Instead of asking her to write it over and over again I figured I could just print it out for each card!
Oh and if anyone is wondering from the ice cube painting project: yes the cube paints work very well on white stretched canvas!
