This is my version of Einet's box:
Her instructions were very clear, and I had no trouble following them:
To start, score a piece of double-sided 12" x 12" cardstock at 3" and 9". Turn the sheet a quarter of a turn, and score at 3", 5 1/2", 8 1/2" and 11".
Adhere Scor-Tape to the center panels, as shown in the photo, and fold in the side tabs.
Remove the paper from the tape, and adhere the center panels to the folded in flaps.
At this point, your box is completed. You may decorate it any way you wish. I just added some candy to the inside, folded over the lid, and added a wide wired ribbon.
You could make this cute little box fit any occasion, simply by changing the cardstock. Here's a Halloween version . . .
