I recently made a birthday card for my brother, who's birthday was on the 7th. It's harder for me to make "boyish" things. Having two girls, I am very good at all things pink and girly, but I never really make things for boys/guys.
This is what I came up with:
Here is a close-up of the buttons and brads I used to dress up the card:
I distressed the edges of the card and the "happy birthday" sign with ink so make them stand out a little more. It's not my best work, but I'm obviously proud enough of it to post it here! :)
