This card on the left uses a standard shipping tag layered on a textured paper of your choice with little rust hearts as an accent.  A cutout from a dictionary pulls it all together by giving the definition of love! 

The card on the right uses round tags for fun!

The bold colors make this card on the left a standout!  Keep the message simple and technique too.  This is stamping and layering.

On the right- more of those clever little round tags layered in a red vellum envelope.

This is what a wonderful piece of marbled paper, a vellum envelope filled with brass charms and a shipping tag can become.  Let your imagination go!
