Somewhere I had seen a card fold similar to this and thought it would be something different from my usual. When I had finished the card I realized that I had the measurements all wrong! When closed the card was supposed to measure 5-1/2" x 4- 1/4" but it measures 4-1/4" square so back to the drawing board! When I get it figured out I will post the dimensions.
I used an Anje Style corner stencil from Marianne Designs for the side panels dry embossed and cut out by hand. On the narrow panels I used a Cuttlebug folder. The 3d sheet is from Nikky.
