This is a 3D project I made with my Hostess Club last month. It is so cute. It holds a fun size candy bar. Here are the dimensions. Hope it makes sense. Take a piece of 3"x4" cardstock and score it 3/4" all the way around. Make a slit on the score line at each corner so that it will make into a box. That is the piece that will hold the candy. For the outer part, you will take a piece of 2 3/4 "x 8" piece and score it at 3 1/4" and at 4 3/4". Take your box and glue inside the outer part and then decorate. I used a piece of 2 1/2 x 3 piece of DSP and the gingerbread man from Scentsational Season. I also put two little holes at the top for the bow and to hold the box together. I know this may be hard to figure out, but I do not know how to put a diagram on here. I guess i can try to make one and take a picture of it. Then it might help you a little more.
Here is a side view of the box. Might make it a little easier to understand the dimensions. I know someone must have come up with the idea, but not sure who? I rec'd one at a swap and she did not say whose idea it was. If someone knows, I would be happy to give that person the credit.
