Card base size, 81/2" x 51/2"{-fold in half to make card base card size 41/4" x 51/2"
Fold the card base in half, along the 51/2" side cut 11/2", width from each end up to the fold line. The front panel will have 3 pieces. and the back will have one. Make matt and layers for decoration. Before adhering, the side matts attach a piece of acetate to the front side panel, to make a bridge that goes over the middle panel.
When the card opens there will be a layer that opens with the two panels on each end joined with the acetate, I have decorated these with the under the sea elements.
The next panel is decorated, and the sentiment is place so that it can be seen when the card is closed.
