Thanks for the lovely comments everyone, even though I feel a bit of a failure. I thought that sketch was going to be so easy - hah! The lettering down the side looked so wrong on the card I'd made and trust me I spent hours trying to make it work.

Wendy the embossing folder, which you will be seeing a lot of because I just love it, is Spellbinders M-Bossabilities Dainty Dots. It's A4 so I can even do 8x8 cards with it by running each side through separately and it has two designs on it. One is the little group of diamond shaped dots you've seen and the other is just ordinary little dots all over. Great value for money.
