For my 7" x 7" wedding card, I made an envelope using our retired "roll" of decorative kraft paper. I kept the flap closed by adding the hearts detail there with dimensionals on the lower half.
For the treat package, which is holding 4 Hershey Nuggets, I used the Detailed Floral thinlits with a space in between the die-cuts large enough to fit the Nuggets. "Next time" I think I'll leave a wider margin of c/s on the left and right sides; it's very fragile.
I did add a strip of Wisteria Wonder c/s underneath the Nuggets to add stability to the piece.
