This traditional Latvian mitten pattern uses three colors of light fingering weight yarn to create a geometric pattern. It has a narrow folded hem at the wrist and may be lined for additional warmth. To change sizes you would change yarn and/or needle sizes, not number of repeats. Single ply wool yarns with a firm twist are traditionally used.
