“Bullet journal collections can be anything,” Silje Sandvik, a bullet journaling enthusiast based in Norway, tells mbg. “Ongoing projects, things you want to focus on, things you want to research, remember or save for later.” Here, Sandvik shares some of her favorite ideas for collections that are as beautiful as they are practical. Sandvik says this one is as fun to look back on as it is to make and can provide a helpful picture of how your mood changes over time. “Use three to six colors—one color for each mood—and color in the circles or squares before going to bed.” Pairing your mood color with a “sentence a day” collection (more on those below) can provide some more context on what triggers you.
