I wanted this to be quite a modern card, but still traditional enough not to make light of the fact that they've been happily married for so long. So I've kept it fresh and simple, but used a very extravagant 'Happy Anniversary' script to posh it up.
The silver heart was hand-drawn and made with silver embossed clear shrink plastic. Note to self - emboss the shape AFTER shrinking, otherwise you end up with an ungodly mess of white hot dripping embossing liquid, which does hurt if it gets on your skin - I have the burn to prove it :-) oops!
The Happy Anniversary was traced onto the card, then black embossed using my glue pen for the powder to stick to. I wish I had such an ornate stamp, but I'm really poor at the moment, what with my naff job and my wedding next week, so I'm improvising!!!
The hole in the card feature was made with nestabilities dies. I did the same on the inside to hide the wire fixing to hold the heart in place.
