When my children were small, I used to take their fingers and stick it in ink and apply it to the greeting card.  I drew little stick figures out of them and put their names next to them (as in this photo).  Everyone loved them and thought it was extra special, and the kids thought that it was fun.  Except it took forever to get the ink off those little fingers. LOL
I used the NEW Bigz Die (Hamburger box) to cut out the hearts from Watercolor Wonder DSP.
