This vest is based on the Mini-Mitered Cardigan. Both patterns can be purchased as one pattern (Mini-Mitered Duo) or individually. Based on a technique credited to Horst Schultz, these mitered corner squares offer countless possibilities in terms of design as well as color. Don’t be daunted by the number of squares-it really is addictive to ‘build” this sweater in two-inch blocks at a time.
