Exploding Boxes

These Two sizes of Exploding Boxes fit so nicely nested together and can be used to hold photos or as a change from a standard birthday card.

You may have seen me demonstrate these on the Pink Frog Create & Craft TV Show. I have given you both imperal and metic measurments so you can create your own.
