I am working on the next project for The Printable Craft Shop, the theme is weddings and I am working with "perfectly and incandescently happy upright diamond fold card" which you can purchase from their page. www.printable-craftshop.com.
I took a piece of cream linen card an folded into an easel car, but added an extra fold in the middle panel to make a concertina style fold. Then matted with gold miri card and then the backing paper.
I did the same for the front panel of the card, and wrapped a cream ribbon around the card.
Below is a picture of the concertina style fold.
This is the finished card.
