BUST's Boobtique sells these delightfully sassy [read: bitchy] Go F*ck Yourself Note Cards for about $17. And I'm pretty sure that I'll be needing to purchase them in the near future.
The set comes with 20 blank cards and envelopes. The cross stitching is simply printed on--no need to bust out any fancy sewing skills here! There are five different malicious card designs (you'll get four of each): Go F*ck Yourself, Irony Is Not Dead, Love Stinks, Bite Me, and Happy F*cking Birthday.
What's not to love? You can choose to send one of these to someone that you actually hate, or to someone who has a sense of humor. Hopefully you know someone who has a sense of humor. If not, find someone with a normal sense of humor and befriend them for the mere purpose of giving them one of these cards.
I can't think of anything better than receiving a "Happy F*cking Birthday" card at a family birthday dinner.
I'd really like to send the "Go F*ck Yourself" card to quite a few people. They'll def come in handy.
