I love this Easter Blossoms stamp set by SU, it's so versatile. I used some retired Groovy Guava textured cardstock and stitched ribbon. The "box" piece is a 12" x 4 1/4" length of cardstock scored at 5" on both ends. Stamp whatever you like on the Top Note die piece and score about a half inch away from center point of die to create box top. There is a hole in the center where the ribbon comes up and out to be tied. This is an easy basic box pattern design from the Stampin' Success magazine. The cello treat bag can be easily inserted in through the side when you are ready.
