Cozy Classroom Mug Warmer

As we transition into autumn and back-to-school season, it's time to make something warm and practical for the coffee-loving students and teachers in your life. This week's challenge is a fitted mug warmer or cup cozy—the perfect small project that works up quickly and makes an excellent gift or classroom staple. Mug warmers are ideal for a 7-day challenge because they're compact, require minimal yarn, and come together in just a few hours of work. You can make multiple versions in different colors and stitch patterns, experiment with textured stitches, or add decorative touches like appliqués or ribbed cuffs. The finished pieces are inherently photogenic—stack them, drape them over mugs, or photograph them in cozy autumn settings. Whether you're a beginner perfecting basic stitch work or an intermediate maker exploring stitch combinations and color blocking, this project invites creative interpretation while staying firmly in the achievable zone for a busy week.
