Paint swatch love notes

Remember my love of paint swatches?  I saw something similar on another blog (for the life of me, I can't remember which blog), so I decided to tweak it a bit and make lunch love notes for lil O and P - whom I will now call Mr. UpCyclist (because of his love of all things cycling).  I bet you can tell which lunch love note is for Mr. U.

Anyway, they are made. They are kind of cute.  Tell me, art majors and art educators of the world, how do I keep the stamped ink from smearing?  Please leave a comment below, email me at jen at or post info on Upcycled Education's Facebook page (the link is to the right).
