I attended a stampin up party recently where we were shown how to make these boxes. Simply take a piece of cardstock and fold it in half and crease the fold. Unfold then fold in half in the other direction mark the centre on each outer edge but do not crease these folds. Now fold into that centre point so you have folded over each corner. Now fold the creased centre line back up and the folded over corners will form the sides. Punch two holes in each side and thread ribbon through here and tie off to hold together.
I stamped a pattern on the cardstock using my autumn leaves stamps and then stamped the same pattern on black tissue paper. I did one set in gold and one in silver and filled these with chocolates for a great gift idea.
