This weekend I was crafting with a group of friends and decided to try it.
The base of the box is only two inches square and the sides are three inches high, so it can be cut from an eight by eight inch square. Score three inches in from each side and cut out the corners leaving a cross shape. One of the corner pieces will make a lid (just add a smidge - two thicknesses of card plus a sliver - to the two inches of the top).
I used one of the smaller dies from the Spellbinders Romantic Rectangles™ on some plain card and used it to frame a pretty floral. These (eight) pieces were stuck on the sides of the box, inside and out.
The lid just had the plain and floral card layered as had the bottom of the inside of the box.
Before sticking the layers together for the bottom of the box, I cut four slits diagonally by each corner and threaded a strip of acetate through each pair; then bent the acetate up and glued on some flowers and butterflies.
I'm afraid I can't remember the name of the person who demonstrated this, but thank you to her.
