The scallop envelope die is such a cute die and when you put two together it makes the cutest little box that can house 2 x 3 inch notecards - I learnt this from my friend Kylie, she made one for a shoebox swap for our team.
I used 2 scallop envelopes from kraft cardstock, then using one of the images from the Tiny Tags stamp set I created a wallpaper effect in White craft ink. Added some DSP in Baja Breeze and stuck down the front of one of the envelopes. Punch a handle in the other envelope flap and some Whisper White taffeta ribbon tied in a bow at the front and voila instant teeny little box.
As I said these boxes fit notecards 2 x 3 inches perfectly (cut cardstock 4 x 3 inches and score at 2 inches). I used the same design as the box on the notecards.
