Use lines from love letters to create subway art. Love this idea! Would be more interesting to look at using more fonts. Maybe use a script type font to make key words pop out and then the script plus red to make the I love you stand out even more.
My boyfriend is totally into chemistry physics and science so this card would be perfect for him! This card would also work for a girl who has the same interests as my boyfriend, you don't want to give this card to someone who doesn't enjoy it!
