Amazing what you can do with a 3 x 3 piece of paper (check the past few days for details on this challenge).
I wrapped a Merci chocolate (no scoring needed) around the chocolate, sealed it closed with tear n tape.
I punch a hole in the top (both front and back).
Then inserted about 20" of ribbon from front to back. The chocolate is pushed down so the ribbon is around the chocolate from top to bottom. Tie a bow. If you pull the bow the chocolate slides up. So it's a mini chocolate slider!
It's tiny, the 3rd photo shows it next to a gift card for perspective.
No measuring, no scoring, easy peasy - I hope you try it - MaryKate
