Mini cards are great because you can make them with left over card stock.
I cut the green card stock:
2-7/8 by 6" and stamped it.

Glue the mini envelope to the card using glue stick. Position the ribbon on the back of the mini envelope.
Create a mini pull for the insert by stapling a small length of 1/4" ribbon
