Without greeting cards, mailboxes would become emotionally starved and attempt to fill the void by snacking on junk mail and returned letters to the Easter Bunny. Coddle your parcel repository with today's Groupon: for $12, you get a 2.5-hour card-making class at Stamp Asylum in Plano (a $25 value).

Stamp Asylum's stationery school equips aspiring card makers with all the necessary supplies and knowledge to craft three custom cards. During each Friday-night class, an experienced stamp sensei teaches technicolor techniques for rendering single-fold salutations or blueberry-muffin ransom notes. Arts-and-crafts accouterments include Tim Holtz distress inks, Hero Arts rubber stamps, cardstock, and all the snippers and adhesives needed to construct Caldecott-medal-winning works of literature. Up to a dozen DIY card designers attend each class, crafting envelope stuffers sized for standard Forever stamps. To enable participants to craft works of art that can evoke emotion from even the most stone-faced clowns, each class includes all of the necessary card-making supplies and tools.
