To celebrate the 50th anniversary of Boutiques La Droguerie, Alice Hammer organized a Mysterious Knit-Along collaborative project. Inspired by the investigations of the famous game Cluedo, each participant chooses to embody a character symbolizing the color of the yarn they will knit. Then they receive their box by mail containing the yarn, instructions to follow to complete this mysterious project, as well as small gifts, a notebook and a tote bag. Each week, two new clues (a tutorial video) containing new information are revealed so participants can continue knitting. They choose between one of the two clues to evolve their design. At the end of the project, 16 designs will be possible based on the clue choices. After several weeks, participants will discover the completed project.
