I'm not as steady at cutting out as the original one. Anyways, here is the original link, it has a template you can use - cut the solid lines and fold the dotted lines. And pay attention. I wasn't concentrating hard enough and cut the bottom of the 'U' when I was meant to stop and fold. Lucky a piece of tape on the underside fixed it but yeah, would have looked a bit better if that cut wasn't there!
Anyways, here is the finished card, minus the soppy message that is now in it. Ok, might have gone a tad overboard with the love heart thing haha but nevermind!
