I recently had to make a few thank you cards and I stumbled across this idea of an exploding card, using the Simply Scored Board made it so simple!
A card measuring 8x8" was scored at 4" both vertically and horizontally and then using the diagonal plate I scored from one corner to the other. This card base was then folded along the score lines as seen in the following picture.
A simple belly band made with ribbon and secured with a layered Mixed Bunch punched flower finished it off.
