Simon Says Stamp with Simon Say Stamp Stamps or Simon Exclusives. I combined stamps from two Kelly Purkey Simon Exclusives (F Bomb and Like A Boss) to make Badges of Encouragement.
For a friend who's fighting cancer, I added "cancer" with a Sharpie. The "like a boss" sentiment has an asterisk before it, but I just wiped that clean after I inked it. The other is for a friend studying for her big nursing test. It'll go on the outside of her gift bag. Safety pins will be attached to the back. The rosette is made with the Tim Holtz Rosette die.
I used CTMH's Petal Ink and Memento Tuxedo Ink.

I think this is the easiest, most secure paper pin back I've done yet. Mark the high parts of the pin back on the cardstock and use a hole punch. Put the pinback through the holes. Apply Glossy Accents to the pinback and the cardstock press down firmly, burnishing right up to the pinback edges.
