I have always been a Neko Case fan - especially when she was hanging out and recording in Tucson.
Check out her kitchen (complete with piano) in Country Living.
The supplies: stamp pad and blank cards. All just things I had.
Thumb down on the stamp pad (and proof I am in desperate need of a manicure).
Final product: thumb print hearts. Pretty darn "cute." Took all of two minutes honestly. Homemade and personal (which I like).
