Lately, you’ve been stewing over the dearth of thank-you notes for generous gifts in your mailbox. And you might explode if selfish roomie doesn’t come up with a birthday card.

Instead of giving pals a piece of your mind, take a more passive-aggressive route: Host a stationery party with Sarah Meyer of Haute Papier.

Just pick the time, date, and style, and Meyer will show up with food, drinks, and project materials (and we’re not talking Ritz crackers and colored construction paper).

She’ll teach everyone to make personalized letterhead with elaborate script and heavy card stock. Whip up invitations for a bridal shower with handmade paper, pressed flowers, and silk ribbon. Or emboss a stack of cards for anytime you need a letter.

Meyer brings enough to ensure everyone can make their own personal stash and sets you up with enough know-how to keep doing it once she’s gone.

You’ll be forever grateful.

Just don’t forget to send a note.
