Last Christmas, 24-year-old British graphic designer Lydia Leith noticed that people had become sick of hearing about the walk-up to April’s royal wedding between Prince William and Kate Middleton. As a pet project, she decided to make Royal Wedding sick bags. “I felt a bit silly because everyone in the printing studio looks at what everyone else is doing,” Leith says. “I thought to myself, ‘What am I doing with my life, printing these sick bags?'”

Leith’s instincts paid off, as the sick bags quickly went viral and became one of the most popular swag items associated with the wedding. Now, the designer has turned her attention on this holiday season, unveiling a new collection of festive-themed sick bags and greeting cards printed with phrases such as “Merry Christmas and a Happy Spew Year.” The colorful creations are, of course, ideal for stuffing stockings and gift giving, but those who overindulged for Thanksgiving yesterday might want to keep one handy, too.
