This package opens like a blossom. Measure a gift's width and height, then draw a cross shape on mat board (center square slightly larger than width, each flap slightly longer than height). Cut out with a utility knife. Score flaps on the colored side. Make box top the same way, but with shorter flaps and a center square 1/8 inch bigger on all sides. Fold all flaps; place gift inside box, and affix top to bottom with a rubber band.
