Very fortuitously, I was asked to make a wedding card just last week, and theme it "silver and diamonds".
My card was actually very straightforward, as it is largely diecuts!
I used a 7 x 5 inch pearlescent ivory card base and onto that I layered a piece of the same card, with some silver card that I ran through my cut n boss machine in the lattice hearts embossing folder matted onto it.
Using the same ivory card, I then cut out the bride and groom figures, the congratulations sentiment and the lattice heart with the birds. All these dies are from Joanna Sheen's range. Additionally, I used a small tattered lace heart. I mounted all of the diecuts except for the tattered lace heart onto the card using thin foam pads - I didn't want them to be too obvious, but did want a little bit of height. The latticed heart didn't show up against the silver lattice background, so I backed it with some scrap ivory card before sticking it on, and it worked a treat.
Next, I chose some "diamond" small adhesive gems and stuck them on the intersections of the lattice in the heart, and at the top of the headdress of my "bride".
Finally, I diecut the intials of the bride and groom using spellbinders alphabet dies, and attached them to the heart.
Because I used heavy base card, it was satisfyingly weighty, and I printed out an insert with a motivational poem on the inside left cover to go inside. To finish it off, I presented it in a narrow box, that was made from the same ivory card.
