I like to wrap presents in stupid but amusing ways.
My dad likes roasted almond chocolate but I felt a bit cheap only getting him that for his birthday. To up the value a bit, I made wrapping paper out of 8 x $5 notes, being careful to stick them together in such a way that they could be easily recovered for their intended use.
Finally, wrapping paper worth keeping.
Fun fact: Photoshop CC will yell at you if you try to open a photograph that contains legal tender.
