What you need:
Brown craft tags (Or cut your own from card stock)
Ink (I love these Clearsnap Colorbox Pigment Paintbox)
Ribbon or twine
Each color of ink in the box separates. You can then use the pad to dab ink onto the stamp.
I used red ink for the flower and then used the alphabet stamps to spell out THANKS in black ink. I love the way the letters look stamped and crooked.
