Here's the how-to on the origami boxes...and, literally, the truffles are as easy as:
melt 8 squares of Baker's chocolate per instructions on the box (microwave for 30 seconds, stir, etc.)
add one 8 ounce package of cream cheese
roll into balls, refrigerate
melt chocolate chips
dip balls into chocolate
I think MamaV's measurements on the truffle box were 8 1/2" x 8 1/2" for the top which means the bottom was 8x8 --- however, with these dimensions our gargantuan truffles only fit three into the box, so we up'd the box size to 8 3/4" square for the top making the bottom 8 1/2 square and we rolled the balls into about a 3/4 teaspoon size balls vs. 1 teaspoon size...
