This is just a simple card - but did you realize that it is one of the ones included free in the Banner Day SVGs that you get when you sign up for an account at Lettering Delights?
I just bought the Snow Pen (made by Marvy Uchida) at Archivers and just had to find a way to try it out. So I made small rivets on the tag. It is very easy - I applied, let it dry and then hit it with the heat embossing tool to puff it up. It worked! I colored the one on the cup with a Copic to match.
