real watercolor brush and some better quality paint and... voila! The secret message was revealed!
With the success of our new paints, Karuna couldn't be stopped. If I hadn't convinced her to take a lunch break, I think she could have gone all day making secret Valentines. I'll remember this next time I need to do some work around the house :)
I'm still intrigued by the idea of giving a secret card with an attached watercolor set. With a nice set, this little baggy would be an awesome goody bag, thank you card, or birthday present. Just write an invisible note and gift away!
